Alarm Troubleshooting

Note The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.

This chapter gives a description, severity, and troubleshooting procedure for each commonly encountered Cisco ONS 15600 alarm and condition. Tables 2-1 through 2-5 provide lists of ONS 15600 alarms organized by severity. Table 2-6 provides a list of alarms organized alphabetically. Table 2-7 gives definitions of all ONS 15600 alarm logical objects, which are the basis of the alarm profile list in Table 2-8. For a comprehensive list of all conditions, refer to the Cisco ONS SONET TL1 Command Guide.

An alarm troubleshooting procedure applies to both the Cisco Transport Controller (CTC) and Transaction Language One (TL1) version of that alarm. If the troubleshooting procedure does not clear the alarm, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call the Cisco Technical Assistance Center (TAC) (1 800 553-2447).

2.1 Alarm Indexes by Default Severity

The following tables group alarms and conditions by their default severities in the ONS 15600 system. These severities are the same whether they are reported in the CTC Alarms window severity (SEV) column or in TL1.

Note The CTC default alarm profile contains some alarms or conditions which are not currently implemented but are reserved for future use.

Note The CTC default alarm profile in some cases contains two severities for one alarm (for example, MJ/MN). The ONS 15600 platform default severity comes first (in this example, MJ), but the alarm can be demoted to the second severity in the presence of a higher-ranking alarm. This is in accordance with Telcordia GR-474-CORE.

2.3 Alarm Logical Objects

The CTC alarm profile list organizes all alarms and conditions according to the logical objects they are raised against. These logical objects represent physical objects such as cards, logical objects such as circuits, or transport and signal monitoring entities such as the SONET optical overhead bits. One alarm can appear in multiple entries. It can be raised against multiple objects. For example, the loss of signal (LOS) alarm can be raised against the optical signal (OC-N) or the building integrated timing supply (BITS) clock as well as other objects. Therefore, both OCN: LOS and BITS: LOS appear in the list (as well as the other objects).

Note Alarm logical object names can appear as abbreviated versions of standard terms used in the system and the documentation. For example, the "OCN" logical object refers to the OC-N signal. Logical object names or industry-standard terms are used within the entries as appropriate.

A card, its physical objects, and logical objects as they are located in any of the eight noncommon card slots. The EQPT object is used for alarms that refer to the card itself and all other objects on the card including ports, lines, synchronous transport signals (STSs), and Virtual Tributaries (VTs).

EXT-SREF

BITS outgoing references (SYNC-BITS1, SYNC-BITS2).

FAN

Fan-tray assembly.

GIGE

Gigabit Ethernet.

NE

The entire network element.

NE-SREF

The timing status of the NE.

OCN

An OC-N line on an OC-N card.

PIM

Pluggable input-output module (or 4PIO) for the ASAP card.

POS

Packet over SONET (virtual entity).

PPM

Pluggable port module (PPM), or Small Form-factor Pluggable (SFP), for the ASAP card.

PS-STS

Protection-switched ONS 15600 STS.

PWR

The node's power supply.

STSMON

STS alarm detection at the monitor point (upstream from the cross-connect).

Note The network element reports alarms or conditions on ingress ports of the card. Alarms detected at the internal ports (TERM side) will be ingress mapped to the MON side. The alarm profile entities of STSMON, if available, should be changed to the same severity as the customized severity for a specific STS alarm.

STSRNG

The STS ring.

STSTERM

STS alarm detection at termination (downstream from the cross-connect).

Note The network element reports alarms or conditions on ingress ports of the card. Alarms detected at the internal ports (TERM side) will be ingress mapped to the MON side. The alarm profile entities of STSTRM, if available, should be changed to the same severity as the customized severity for a specific STS alarm.

2.4 Alarm List by Logical Object Type

Table 2-8 lists all ONS 15600 Software Release 7.0 alarms and logical objects as they are given in the system alarm profile. The list entries are organized logical object name and then by alarm or condition name. Each entry refers to an alarm description in this chapter. Where appropriate, the alarm entries also contain troubleshooting procedures.

Note In a mixed network containing different types of nodes (such as an ONS 15310-CL, ONS 15454, and ONS 15600), the initially displayed alarm list in the Provisioning > Alarm Profiles > Alarm Profile Editor tab lists all conditions that are applicable to all nodes in the network. However, when you load the default severity profile from a node, only applicable alarms will display severity levels. Nonapplicable alarms can display "use default" or "unset."

Note In some cases this list does not follow alphabetical order, but it does reflect the order shown in CTC.

2.5 Trouble Notifications

The ONS 15600 system reports trouble by utilizing standard alarm and condition characteristics, standard severities following the rules in Telcordia GR-253-CORE, and graphical user interface (GUI) state indicators. These notifications are described in the following paragraphs.

The ONS 15600 uses standard Telcordia categories to characterize levels of trouble. The system reports trouble notifications as alarms and status or descriptive notifications (if configured to do so) as conditions in the CTC Alarms window. Alarms typically signify a problem that the user needs to remedy, such as a loss of signal. Conditions do not necessarily require troubleshooting.

2.5.1 Alarm Characteristics

The ONS 15600 uses standard alarm entities to identify what is causing trouble. All alarms stem from hardware, software, environment, or operator-originated problems whether or not they affect service. Current alarms for the network, CTC session, node, or card are listed in the Alarms tab. (In addition, cleared alarms are also found in the History tab.)

2.5.2 Condition Characteristics

Conditions include any problem detected on an ONS 15600 shelf. They might include standing or transient notifications. A snapshot of all current raised, standing conditions on the network, node, or card can be retrieved in the CTC Conditions window or using TL1's set of RTRV-COND commands. (In addition, some but not all cleared conditions are also found in the History tab.)

For a comprehensive list of all conditions, refer to the Cisco ONS SONET TL1 Command Guide. For a comprehensive list of all transient conditions, see Chapter 3 "Transient Conditions."

•A Major (MJ) alarm is a serious alarm, but the trouble has less impact on the network. For example, loss of traffic on more than five DS-1 circuits is Critical (CR), but loss of traffic on one to four DS-1 circuits is Major (MJ).

•Minor (MN) alarms generally are those that do not affect service. For example, the automatic protection switching (APS) byte failure (APSB) alarm indicates that line terminating equipment (LTE) detects a byte failure on the signal that could prevent traffic from properly executing a traffic switch.

•Not Alarmed (NA) conditions are information indicators, such as for the free-running synchronization (FRNGSYNC) state or forced-switch to primary timing source (FRCSWTOPRI) event. They might or might not require troubleshooting, as indicated in the entries.

•Not Reported (NR) conditions occur as a secondary result of another event. For example, the alarm indication signal (AIS), with severity NR, is inserted by a downstream node when an LOS (CR or MJ) alarm occurs upstream. These conditions do not in themselves require troubleshooting, but are to be expected in the presence of primary alarms.

Severities can be customized for an entire network or for single nodes, from the network level down to the port level by changing or downloading customized alarm profiles. These custom severities are subject to the standard severity-demoting rules given in Telcordia GR-474-CORE and shown in the Alarm Hierarchy section. Procedures for customizing alarm severities are located in the "Manage Alarms" chapter in the Cisco ONS 15600 Procedure Guide.

2.5.4 Alarm Hierarchy

All alarm, condition, and unreported event severities listed in this manual are default profile settings. However in situations when traffic is not lost, such as when the alarm occurs on protected ports or circuits, alarms having Critical (CR) or Major (MJ) default severities can be demoted to lower severities such as Minor (MN) or Non-Service-Affecting (NSA) as defined in Telcordia GR-474-CORE.

A path alarm can be demoted if a higher-ranking alarm is raised for the same object. For example, If a path trace identifier mismatch (TIM-P) is raised on a circuit path and then a loss of pointer on the path (LOP-P) is raised on the path, the LOP-P alarm stands and the TIM-P closes. The hierarchy of path alarms in the ONS 15600 system is shown in Table 2-9.

Table 2-9 Path Alarm Hierarchy

Priority

Condition Type

Highest

AIS-P

—

LOP-P

—

UNEQ-P

Lowest

TIM-P

Facility (port) alarms also follow a hierarchy, which means that lower-ranking alarms are closed by higher-ranking alarms. The hierarchy of facility alarms in the ONS 15600 system is shown in Table 2-10.

Near-end failures and far-end failures follow different hierarchies. Near-end failures stand according to whether they are for the entire signal (LOS, LOF), facility (AIS-L, etc.), path (AIS-P, etc.) or VT (AIS-V, etc.). The full hierarchy for near-end failures is shown in Table 2-11. This table is taken from Telcordia GR-253-CORE.

2.5.6 States

The Alarms and History tab State (ST) columns indicate the disposition of alarms and conditions as follows:

•A raised (R) event is one that is active.

•A cleared (C) event is one that is no longer active.

•A transient (T) event is one that is automatically raised and cleared in CTC during system changes such as user login, logout, loss of connection to node view, etc. Transient events do not require user action. These are listed in Chapter 3 "Transient Conditions."

2.5.7 Safety Summary

This section covers safety considerations to ensure safe operation of the ONS 15600 system. Personnel should not perform any procedures in this manual unless they understand all safety precautions, practices, and warnings for the system equipment. Some troubleshooting procedures require installation or removal of cards. In these instances, users should pay close attention to the following caution:

Caution Hazardous voltage or energy might be present on the backplane when the system is operating. Use caution when removing or installing cards.

Some troubleshooting procedures require installation or removal of optical cards. In these instances, users should pay close attention to the following warnings:

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Warning Class 1 laser product. Statement 1008

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Warning The power supply circuitry for the equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment. Statement 207

2.6 Alarm Procedures

This section lists alarms alphabetically and includes some conditions commonly encountered when troubleshooting alarms. The severities, descriptions, and troubleshooting procedures accompany alarms and conditions.

Note When an entity is put in the Out of Service and Maintenance (OOS,MT) administrative state, the ONS 15600 suppresses all standing alarms on that entity. All alarms and events appear on the Conditions tab. You can change this behavior for the LPBKFACILITY, LPBKPAYLD, and LPBKTERMINAL alarms. To display these alarms on the Alarms tab, set the NODE.general.ReportLoopbackConditionsOnPortsInOOS-MT to TRUE on the NE Defaults tab.

2.6.1 AIS

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

Logical Object: BITS

The Alarm Indication Signal (AIS) condition indicates that this node is detecting an alarm indication signal in the incoming signal SONET overhead.

Generally, any AIS is a special SONET signal that communicates to the receiving node when the transmit node does not send a valid signal. AIS is not considered an error. It is raised by the receiving node on each input when the node sees the AIS instead of a real signal. In most cases when this condition is raised, an upstream node is raising an alarm to indicate a signal failure; all nodes downstream from it only raise some type of AIS. This condition clears when you resolved the problem on the upstream node.

Clear the AIS Condition

Step 1 Determine whether there are alarms on the upstream nodes and equipment, especially the "LOS (OCN)" alarm on page 2-86 or if there are out-of-service (OOS,MT or OOS,DSBLD) ports.

Step 2 Clear the upstream alarms using the applicable procedures in this chapter.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.2 AIS-L

Default Severity: Nor Reported (NR), Non-Service-Affecting (NSA)

Logical Object: OCN

The AIS Line condition indicates that this node is detecting line-level AIS in the incoming signal. This alarm is secondary to another alarm occurring simultaneously in an upstream node.

Clear the AIS-P Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.4 APSB

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The APS Channel Byte Failure alarm occurs when LTE detects protection switching byte failure or an invalid switching code in the incoming APS signal. Some older SONET nodes not manufactured by Cisco send invalid APS codes if they are configured in a 1+1 protection scheme with newer SONET nodes, such as the ONS 15600. These invalid codes cause an APSB alarm on an ONS 15600.

Note APS switches are hitless on the ONS 15600.

Clear the APSB Alarm

Step 1 Use an optical test set to examine the incoming SONET overhead to confirm inconsistent or invalid K bytes. For specific procedures to use the test set equipment, consult the manufacturer. If corrupted K bytes are confirmed and the upstream equipment is functioning properly, the upstream equipment might not interoperate effectively with the ONS 15600.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 If the alarm does not clear and the overhead shows inconsistent or invalid K bytes, you might need to replace the upstream cards for protection switching to operate properly. Complete the "Replace an I/O Card" procedure.

Caution For the ONS 15600, removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. See the
"Verify or Create Node DCC Terminations" section for commonly used alarm troubleshooting procedures.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.5 APSCDFLTK

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The APS Default K Byte Received alarm occurs when a bidirectional line switched ring (BLSR) is not properly configured—for example, when a four-node BLSR has one node configured as a path protection. When this misconfiguration occurs, a node in a path protection or 1+1 configuration does not send the two valid K1/K2 APS bytes anticipated by a system configured for BLSR. One of the bytes sent is considered invalid by the BLSR configuration. The K1/K2 byte is monitored by receiving equipment for link-recovery information.

Step 4 If the alarm does not clear, verify correct configuration of east port and west port optical fibers. (See the "E-W-MISMATCH" alarm on page 2-49.) West port fibers must connect to east port fibers and east port fibers must connect to west port fibers. The "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide contains procedures for fibering a BLSR.

Step 5 If the alarm does not clear and if the network is a four-fiber BLSR, ensure that each protect fiber is connected to another protect fiber and each working fiber is connected to another working fiber. The software does not report any alarm if a working fiber is incorrectly attached to a protect fiber.

•Codes that are irrelevant to the specific protection switching operation being requested.

•Requests that are irrelevant to the ring state of the ring (such as a span protection switch request in a two-fiber ring NE).

•ET code in K2 bits 6 through 8 received on the incoming span, but not sourced from the outgoing span.

Note This alarm can occur on a VT tunnel when it does not have VT circuits provisioned on it. It can also occur when the exercise command or a lockout is applied to a span. An externally switched span does not raise this alarm because traffic is preempted.

Note The APSC-IMP alarm may be raised on a BLSR or MS-SPRing when a drop connection is part of a cross-connect loopback.

Note The APSC-IMP alarm may be momentarily raised on BLSR spans during PCA circuit creation or deletion across multiple nodes using CTC.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Clear the APSC-IMP Alarm

Step 1 Use an optical test set to determine the validity of the K byte signal by examining the received signal. For specific procedures to use the test set equipment, consult the manufacturer.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

If the K byte is invalid, the problem lies with upstream equipment and not with the reporting ONS 15600. Troubleshoot the upstream equipment using the procedures in this chapter, as applicable. If the upstream nodes are not ONS 15600s, consult the appropriate user documentation.

Step 5 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.7 APSCINCON

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

An APS Inconsistent alarm means that an inconsistent APS byte is present. The SONET overhead contains K1/K2 APS bytes that notify receiving equipment, such as the ONS 15600, to switch the SONET signal from a working to a protect path when necessary. An inconsistent APS code occurs when three consecutive frames contain nonidentical APS bytes, which in turn give the receiving equipment conflicting commands about switching.

Clear the APSCINCON Alarm

Step 2 If an APSINCON alarm occurs with no other alarms, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.8 APSCM

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: OCN

The APS Channel Mismatch alarm occurs when the ONS system expects a working channel but receives a protect channel. In many cases, the working and protect channels are crossed and the protect channel is active. If the fibers are crossed and the working line is active, the alarm does not occur. The APSCM alarm occurs only on the ONS system when bidirectional protection is used on OC-N cards in a 1+1 configuration.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Note APS switches are hitless in the ONS 15600.

Clear the APSCM Alarm

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 If the fibers are correctly connected, verify that the protection-card channel fibers are physically connected directly to the adjoining node's protection-card channel fibers.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

2.6.9 APSCNMIS

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: OCN

The APS Node ID Mismatch alarm occurs when the source node ID contained in the incoming APS channel K2 byte is not present in the ring map. The APSCNMIS alarm could occur and clear when a BLSR is being provisioned. If so, you can disregard the temporary occurrence. If the APSCNMIS remains, the alarm clears when a K byte with a valid source node ID is received.

Step 7 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

2.6.10 APSIMP

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The APS Invalid Mode condition occurs if a 1+1 protection group is not properly configured at both nodes to send or receive the correct APS byte. A node that is either configured for no protection or is configured for path protection or BLSR protection does not send the right K2 APS byte anticipated by a system configured for 1+1 protection. The 1+1 protect port monitors the incoming K2 APS byte and raises this alarm if it does not receive the byte.

The condition is superseded by an APSCM or APSMM alarm, but not by an AIS condition. It clears when the port receives a valid code for 10 ms.

Clear the APSIMP Condition

Step 1 Check the configuration of the other node in the 1+1 protection group. If the far end is not configured for 1+1 protection, create the group. For instructions, refer to the "Turn Up Node" chapter in the Cisco ONS 15600 Procedure Guide.

Step 2 If the other end of the group is properly configured or the alarm does not clear after you have provisioned the group correctly, verify that the working ports and protect ports are cabled correctly.

Step 3 Ensure that both protect ports are configured for SONET.

Step 4 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.11 APSMM

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

An APS Mode Mismatch failure alarm occurs on traffic (OC-N) facilities when there is a mismatch of the protection switching schemes at the two ends of the span, such as being bidirectional at one end and unidirectional at the other. Each end of a span must be provisioned the same way: bidirectional and bidirectional, or unidirectional and unidirectional. The alarm can also occur if a vendor's equipment (other than Cisco) is provisioned as 1:N and the ONS 15600 is provisioned as 1+1.

If one end is provisioned for 1+1 protection switching and the other is provisioned for path protection switching, an APSMM alarm occurs in the ONS 15600 node that is provisioned for 1+1 protection switching.

Clear the APSMM Alarm

Step 1 For the reporting ONS system, display node view and verify the protection scheme provisioning by completing the following steps:

a. Click the Provisioning > Protection tabs.

b. Click the 1+1 protection group configured for the OC-N cards.

The chosen protection group is the protection group optically connected (with DCC connectivity) to the far end.

c. Click Edit.

d. Record whether the Bidirectional Switching check box is checked.

Step 2 Click OK in the Edit Protection Group dialog box.

Step 3 Log into the far-end node and verify that the OC-N 1+1 protection group is provisioned.

Step 4 Verify that the Bidirectional Switching check box matches the checked or unchecked condition of the box recorded in Step 1. If not, change it to match.

Step 5 Click Apply.

Step 6 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.12 AUD-LOG-LOSS

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: NE

The Audit Trail Log Loss condition occurs when the log is 100 percent full and that the oldest entries are being replaced as new entries are generated. The log capacity is 640 entries. The log must be off-loaded using the following procedure to make room for more entries.

Clear the AUD-LOG-LOSS Condition

Step 1 In node view, click the Maintenance > Audit tabs.

Step 2 Click Retrieve.

Step 3 Click Archive.

Step 4 In the Archive Audit Trail dialog box, navigate to the directory (local or network) where you want to save the file.

Step 5 Enter a name in the File Name field.

You do not have to assign an extension to the file. It is readable in any application that supports text files, such as WordPad, Microsoft Word (imported), etc.

Step 6 Click Save.

The 640 entries are saved in this file. New entries continue with the next number in the sequence, rather than starting over.

Step 7 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.13 AUD-LOG-LOW

Note AUD-LOG-LOW is an informational condition. It does not require troubleshooting.

2.6.14 AUTORESET

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Automatic System Reset alarm occurs when you change an IP address or perform any other operation that causes an automatic card-level reboot.

Note If an optical card associated with an active port in a 1+1 protection group resets, all DCC traffic terminated or tunneled on the active port is lost while the card resets. No DCC traffic is lost during a reset of an optical card associated with a standby port.

Clear the AUTORESET Alarm

Step 1 Determine whether there are additional alarms that could have triggered an automatic reset. If there are, troubleshoot these alarms using the applicable section of this chapter.

Step 2 If the card automatically resets more than once a month with no apparent cause, complete the "Replace an I/O Card" procedure. If the lack of communication continues, the AUTORESET alarm is cleared and the EQPT-BOOT alarm occurs. In this case, no AUTORESET troubleshooting is required.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Caution For the ONS 15600, removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this, perform an external switch if a switch has not already occurred. See the
"Protection Switching, Lock Initiation, and Clearing" section for commonly used traffic-switching procedures.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.15 AUTOSW-AIS

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

Logical Object: STSMON

The Automatic UPSR Switch Caused by an AIS condition indicates that automatic path protection switching occurred because of an AIS condition. If the path protection is configured for revertive switching, it reverts to the working path after the fault clears. The AIS also clears when the upstream trouble is cleared.

Note This condition is only reported if the path protection is set up for revertive switching.

Generally, any AIS is a special SONET signal that communicates to the receiving node when the transmit node does not send a valid signal. AIS is not considered an error. It is raised by the receiving node on each input when it detects the AIS instead of a real signal. In most cases when this condition is raised, an upstream node is raising an alarm to indicate a signal failure; all nodes downstream from it only raise some type of AIS. This condition clears when you resolve the problem on the upstream node.

Clear the AUTOSW-AIS Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.26 CIDMISMATCH-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

A Connection ID Mismatch on SSXC A (in Slot 6) alarm occurs when at least one internal connection ID mismatch is present at the STS-1 level on the traffic (OC-N) card outbound data path.

The alarm occurs under the following conditions:

•Head end of the connection between traffic cards is removed.

•VT tunnel if it does not have VT circuits provisioned on it.

•Circuit is not provisioned completely in an open ended STS circuit.

Note When an alarm includes a numeric or alphabetical designation, it indicates whether the alarm applies to the first or second card of a specific type on the shelf. A zero or A indicates that the alarm occurs against the first card of its type, from left to right, in the shelf. A one or B indicates that the alarm occurs against the second card of its type in the shelf.

Clear the CIDMISMATCH-A Alarm

Step 1 Depending on how many CIDMISMATCH alarms are raised, take one of the following actions:

To determine which SSXC card is the preferred copy and if it is currently being used, in node view click the Maintenance > Preferred Copy tabs. The Data Copy area Preferred field shows Copy A or Copy B. The Currently Used field shows the copy being used.

Note In CTC, Copy A refers to the SSXC card in Slot 6. Copy B refers to the SSXC card in Slot 8. Either copy can be chosen as the preferred copy SSXC card. The other SSXC card is called the alternate SSXC card in this chapter.

•A 1+1 APS is identified in the node view Maintenance > Protection tab. If you click the protection group, under the Selected Group list, the ports are designated as Working/Standby and Protect/Active.

Clear the CIDMISMATCH-B Alarm

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.28 CLKFAIL

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: EQPT

The Clock Fail alarm occurs when an internal clock module fails. If this alarm occurs against the standby TSC card, the card must be replaced. If the alarm occurs against the active TSC card, the card automatically becomes standby because the traffic and SSXC cards can only take timing from the active TSC card.

Clear the CLKFAIL Alarm

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Note When there are different versions of system software on the two TSC cards, it takes approximately 20 minutes for the active TSC card to transfer the system software to the newly installed standby TSC card. When the transfer completes, the TSC card reboots and goes into standby mode after approximately three minutes.

Note If the active and standby TSC cards have the same versions of software, it takes approximately three minutes for software to be updated on a standby TSC card.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.29 CONTBUS-CLK-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

An Inbound Interconnection Timing Control Bus 0 Failure alarm on the Slot 10 TSC card occurs if the timing signal from the Slot 5 TSC card has an error. If the Slot 10 TSC card and all other cards on the shelf raise this alarm, the alarm processor on the Slot 5 TSC card clears the alarm on the other cards and raises this alarm against the Slot 5 TSC card only.

2.6.30 CONTBUS-CLK-B

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

An Inbound Interconnection Timing Control Bus 1 Failure alarm on the Slot 5 TSC card occurs if the timing signal from the Slot 10 TSC card has an error. If the Slot 5 TSC card and all other cards on the shelf raise the alarm, the processor on the Slot 10 TSC card clears the alarm on the other cards and raises this alarm against the Slot 10 TSC card only.

Note When an alarm includes a numeric or alphabetical designation, it indicates whether the alarm applies to the first or second card of a specific type on the shelf. A zero or A indicates that the alarm occurs against the first card of its type, from left to right, in the shelf. A one or B indicates that the alarm occurs against the second card of its type in the shelf.

Clear the CONTBUS-CLK-B Alarm

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

Logical Object: EQPT

A TSC Card A to Shelf A Slot Communication Failure alarm occurs when the active Slot 5 TSC card (TSC card A) has lost communication with another card in the shelf. The other card is identified by the Object column in the CTC alarm window.

The CONTBUS-IO-A alarm can appear briefly when the ONS 15600 switches to the standby TSC card. In the case of a TSC card protection switch, the alarm clears after the other cards establish communication with the newly active TSC card. If the alarm persists, the problem lies with the physical path of communication from the TSC card to the reporting card. The physical path of communication includes the TSC card, the other card, and the backplane.

Clear the CONTBUS-IO-A Alarm

Step 1 Ensure that the reporting card is physically present in the shelf. Record the card type. Click the Inventory tab and view the Eqpt Type column to display the provisioned type.

If the actual card type and the provisioned card type do not match, see the "MEA" alarm on page 2-95 for the reporting card.

Logical Object: EQPT

A TSC Card B to Shelf Communication Failure alarm occurs when the active Slot 10 TSC card (TSC card B) has lost communication with another card in the shelf. The other card is identified by the Object column in the CTC alarm window.

The CONTBUS-IO-B alarm might appear briefly when the ONS 15600 switches to the protect TSC card. In the case of a TSC card protection switch, the alarm clears after the other cards establish communication with the newly active TSC card. If the alarm persists, the problem lies with the physical path of communication from the TSC card to the reporting card. The physical path of communication includes the TSC card, the other card, and the backplane.

Clear the CONTBUS-IO-B Alarm

Step 1 Ensure that the reporting card is physically present in the shelf. Record the card type. Click the Inventory tab and view the Eqpt Type column to display the provisioned type.

If the actual card type and the provisioned card type do not match, see the "MEA" alarm on page 2-95 for the reporting card.

2.6.33 CONTCOM

The Interconnection Control Communication Failure alarm occurs when the internal messaging processor on the reporting active TSC card fails.

A TSC card should boot and be in the ready state within approximately five minutes. If the CONTCOM alarm clears within this time frame and the TSC card goes to standby or active mode as applicable, no action is necessary.

If the communication equipment on the backplane fails, a CONTBUS alarm occurs instead of a CONTCOM alarm.

2.6.34 CTNEQPT-PB-A

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: EQPT

The SSXC-0 Data Payload Bus Interconnect Failure alarm occurs when the data path interconnection between equipment from SSXC-0 (Slot 6) to inbound or outbound traffic (OC-N) card slots has a failure. The SSXC card and the reporting card are no longer communicating through the backplane. The problem exists in the SSXC card, the reporting traffic card, or the backplane. If more than one traffic card on the shelf raises this alarm, the TSC card clears this alarm on the traffic cards and raises it alarm against SSXC-0.

Note When an alarm includes a numeric or alphabetical designation, it indicates whether the alarm applies to the first or second card of a specific type on the shelf. A zero or A indicates that the alarm occurs against the first card of its type, from left to right, in the shelf. A one or B indicates that the alarm occurs against the second card of its type in the shelf.

Note If you insert a new TSC card that has the same version of software as the active and standby TSC card, it takes approximately three minutes for the standby TSC card to become available.

Note It takes approximately 20 minutes for the active TSC card to transfer the system software to the newly installed TSC card. Software transfer occurs in instances where different software versions exist on the two cards. When the transfer completes, the TSC card reboots and goes into standby mode after approximately three minutes.

Clear the CTNEQPT-PB-A Alarm

Step 1 If the alarm occurs against a single traffic (OC-N) card, continue with Step 2. If the alarm occurs against multiple traffic cards, it indicates a problem with the SSXC card. Continue with Step 6.

Step 2 If the traffic card ports are part of a path protection, switch the single circuit on the span using instructions in the "Maintain the Node" chapter in the Cisco ONS 15600 Procedure Guide. If the ports are part of a 1+1 protection group, complete the "Initiate a 1+1 Protection Port Force Switch Command" procedure.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Note If the traffic card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port. Refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions. Label the bad port and take it out of service until the card can be replaced.

Step 6 If you replace the traffic card and the alarm does not clear, an SSXC card problem is indicated. If an automatic switch to the alternate copy SSXC card occurred, the SSXC card can be serviced. If traffic has not switched, request a preferred copy switch by completing the "Request a Cross-Connect Card Preferred Copy Switch" procedure.

To determine which SSXC card is the preferred copy and whether it is currently being used, in node view go to the Maintenance > Preferred Copy window. The Data Copy area Preferred field shows Copy A or Copy B. The Currently Used field shows the copy being used.

Note In CTC, Copy A refers to the SSXC card in Slot 6. Copy B refers to the SSXC card in Slot 8. Either copy might be chosen as the preferred copy SSXC card. The other SSXC card is called the alternate SSXC card in this chapter.

Step 10 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

Step 11 Depending on which card raised the alarm, perform the following actions:

Note If an automatic switch to the alternate copy SSXC card occurred, traffic is automatically restored to the preferred copy.

2.6.40 DUP-IPADDR

Default Severity: Minor (MN), Non-Service Affecting (NSA)

Logical Object: NE

The Duplicate IP Address alarm indicates that the alarmed node IP address is already in use within the same DCC area. When this happens, CTC no longer reliably connects to either node. Depending on how the packets are routed, CTC could connect to either node (having the same IP address). If CTC has connected to both nodes before they shared the same address, it has two distinct NodeModel instances (keyed by the node ID portion of the MAC address).

Clear the DUP-IPADDR Alarm

Step 1 Isolate the alarmed node from the other node having the same address by completing the following steps:

a. Connect to the alarmed node using the Craft port on the ONS 15600 chassis.

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The SONET DCC Termination Failure alarm occurs when the ONS 15600 loses its DCC. Although this alarm is primarily SONET, it can apply to dense wavelength division multiplexing (DWDM) in other platforms.

The Section DCC (SDCC) consists of three bytes, D1 through D3, in the SONET overhead. The bytes convey information about operation, administration, maintenance, and provisioning (OAM&P). The ONS 15600 uses the DCC on the SONET Section layer to communicate network management information.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Note If a circuit shows an incomplete state when this alarm is raised, the logical circuit is in place. The circuit is able to carry traffic when the connection issue is resolved. You do not need to delete the circuit when troubleshooting this alarm.

Step 3 If the alarm does not clear on the reporting node, verify the physical connections between the cards and that the fiber-optic cables are configured to carry SDCC traffic. If they are not, correct them. For more information about fiber connections and terminations, refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

If the physical connections are correct and configured to carry DCC traffic, ensure that both ends of the fiber span have In-Service and Normal (IS-NR) ports. Verify that the SRV LED on each OC-N card is green.

Step 6 If DCC is provisioned for the ends of the span, verify that the port is active and in service by completing the following steps:

a. Confirm that the OC-N card shows a green LED in CTC or on the physical card.

A green SRV LED indicates an active card.

b. To determine whether the port is in service, double-click the card in CTC to display the card view.

c. Click the Provisioning > Line tabs.

d. Verify that the Admin State column lists the port as IS.

e. If the Admin State column lists the port as OOS,MT or OOS,DSBLD, click the column and click IS from the drop-down list. Click Apply.

Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is either raised or remains, and the port service state transitions to OOS-AU,FLT.

Step 7 For all nodes, if the card is in service, use an optical test set to determine whether signal failures are present on fiber terminations. For specific procedures to use the test set equipment, consult the manufacturer.

Step 9 If budget loss is within parameters, ensure that fiber connectors are securely fastened and properly terminated. For more information refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide.

Wait ten minutes to verify that the card you reset completely reboots and becomes the standby card.

Resetting the active TSC card switches control to the standby TSC card. If the alarm clears when the ONS 15600 node switches to the standby TSC card, the user can assume that the previously active card is the cause of the alarm.

Step 11 If the TSC card reset does not clear the alarm, delete the problematic SDCC termination by completing the following steps:

a. From card view, click View > Go to Previous View if you have not already done so.

b. Click the Provisioning > Comm Channels > SDCC tabs.

c. Highlight the problematic DCC termination.

d. Click Delete.

e. Click Yes in the Confirmation Dialog box.

Step 12 Recreate the SDCC termination. Refer to the "Turn Up Network" chapter in the Cisco ONS 15600 Procedure Guide for instructions.

Step 13 Verify that both ends of the DCC have been recreated at the optical ports.

2.6.44 EOC-L

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The Line DCC Termination Failure alarm occurs when the ONS 15600 loses its line DCC termination. The line DCC (LDCC) consists of nine bytes, D4 through D12, in the SONET overhead. The bytes convey information about OAM&P. The ONS 15600 uses the LDCCs on the SONET line layer to communicate network management information.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Note If a circuit shows a partial status when the EOC or EOC-L alarm is raised, it occurs when the logical circuit is in place. The circuit is able to carry traffic when the DCC termination issue is resolved. You do not need to delete the circuit when troubleshooting this alarm.

Clear the EOC-L Alarm

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

2.6.53 E-W-MISMATCH

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: OCN

A Procedural Error Misconnect East/West Direction alarm occurs during BLSR setup, or when nodes in a ring have slots misconnected. An east slot can be misconnected to another east slot, or a west slot can be misconnected to another west slot. In most cases, the user did not connect the fibers correctly or the ring provisioning plan was flawed. You can physically reconnect the cable to the correct slots to clear the E-W-MISMATCH alarm. Alternately, you can delete and recreate the span in CTC to change the west line and east line designations. The CTC method clears the alarm, but could change the traditional east-west node connection pattern of the ring.

Note The E-W-MISMATCH alarm also appears during the initial set up of a ring with its East-West slots configured correctly. If the alarm appears during the initial setup, the alarm clears itself shortly after the ring setup is complete.

Note The lower-numbered slot at a node is traditionally labeled the west slot and the higher numbered slot is labeled the east slot. For example, in the ONS 15600 system, Slot 2 is west and Slot 12 is east.

Note The physical switch procedure is the recommend method of clearing the E-W-MISMATCH alarm. The physical switch method reestablishes the logical pattern of connection in the ring. However, you can also use CTC to recreate the span and identify the misconnected slots as east and west. The CTC method is useful when the misconnected node is not geographically near the troubleshooter.

Clear the E-W-MISMATCH Alarm with a Physical Switch

Step 1 Diagram the ring setup, including nodes and spans, on a piece of paper or white board.

Step 2 In node view, click View > Go to Network View.

Step 3 Label each of the nodes on the diagram with the same name that appears on the network map.

Step 4 Right-click each span to display the node name/slot/port for each end of the span.

Step 7 Label the highest slot at each node east and the lowest slot at each node west.

Step 8 Examine the diagram. You should see a clockwise pattern of west slots connecting to east slots for each span. Refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guidefor more information about cable installation in the system.

Step 9 If any span has an east-to-east or west-to-west connection, physically switching the fiber connectors from the card that does not fit the pattern to the card that continues the pattern should clear the alarm.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

2.6.60 FAILTOSW

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Failure to Switch to Protection Facility condition occurs when a working or protect electrical facility switches to its companion port by using a MANUAL command. For example, if you attempt to manually switch traffic from an unused protect port to an in-service working port, the switch will fail (because traffic is already present on the working port) and you will see the FAILTOSW condition.

Clear the FAILTOSW Condition

Step 1 Look up and troubleshoot the higher-priority alarm. Clearing the higher-priority condition frees the card and clears the FAILTOSW.

Step 2 If the condition does not clear, replace the working electrical (traffic) card that is reporting the higher priority alarm by following the correct replacement procedure in the "2.8.4 Physical Card Reseating, Resetting, and Replacement" procedure. This card is the working electrical card using the protect card and not reporting FAILTOSW.

Replacing the working electrical card that is reporting the higher-priority alarm allows traffic to revert to the working slot and the card reporting the FAILTOSW to switch to the protect card.

Note If an ONS 15600 traffic (OC-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port; refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions. Label the bad port, and place it out of service until such time as the card can be replaced.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

Step 2 If the alarm does not clear, physically check the fiber connections to the card and ports to ensure that they are securely fastened and intact. For more information about fiber connections and terminations, refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 3 Clear the attempted switch by completing the following steps:

a. In node view, click the Circuits > Circuits tabs.

b. Highlight the path where you tried to perform the switch. In the Switch State column, verify that the state is Clear. If it is not, select Clear from the list.

c. Click Apply.

Step 4 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447). If the alarm was reported against the ONS 15600, it is Service-Affecting (SA) and should be reported.

2.6.62 FAILTOSWR

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

Note FRCDSWTOTHIRD is an informational condition. It does not require troubleshooting.

2.6.87 FREQ-MISMATCH

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Frequency Mismatch alarm occurs when one of the two TSC cards has a timing module failure that causes an inconsistency between the TSC card timing frequencies. This alarm can be caused by the active or standby TSC card.

The ONS 15600 checks timing frequency synchronization in 83-minute (1 hour and 23 minutes) cycles. The FREQ-MISMATCH alarm occurs if two consecutive timing check cycles show frequency mismatches. The alarm is cleared if one cycle shows a timing frequency match between the TSC cards.

Clear the FREQ-MISMATCH Alarm

Step 2 Wait for two intervals of 83 minutes (2 hours and 46 minutes) and check the node view Alarms tab to see whether the alarm is cleared.

During the initial 83-minute synchronization check cycle while the replacement standby TSC card is booting up, the replacement TSC card is attaining the timing from the BITS or internal source so it is normal that the two TSC cards are not synchronized. The ONS 15600 system disregards the result of this check cycle and begins keeping track of synchronization in the second 83-minute cycle. If the result of the cycle shows that the TSC cards are synchronized properly, the alarm is cleared.

Step 3 If the FREQ-MISMATCH alarm did not clear after two timing check cycles, it means that the second timing cycle resulted in a mismatch. Wait a third 83-minute cycle and check the alarm again.

If the alarm has cleared, it means a third cycle showed that the TSC card timing modules were synchronized. If the alarm remains, it means that the ONS 15600 system has had two frequency mismatch cycles, and indicates a problem with the other TSC card.

Step 6 Wait for three intervals of 83 minutes (4 hours and 9 minutes) and check CTC to see if the FREQ-MISMATCH alarm has recurred. If it has not recurred, the problem is solved.

Step 7 If the alarm has recurred after both TSC cards have been replaced, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.88 FRNGSYNC

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: NE-SREF

The Free Running Synchronization Mode condition occurs when the reporting ONS 15600 is in free-run synchronization mode. External timing sources have been disabled and the node is using its internal clock, or the node has lost its designated BITS timing source. After the 24-hour holdover period expires, timing slips could begin to occur on an ONS 15600 node relying on an internal clock.

Note If the ONS 15600 is configured to operate from its internal clock, disregard the FRNGSYNC condition.

Clear the FRNGSYNC Condition

Step 1 If the ONS 15600 is configured to operate from an external timing source, verify that the BITS timing source is valid. Common problems with a BITS timing source include reversed wiring and bad timing cards. Refer to the "Timing" chapter in the Cisco ONS 15600 Reference Manual for more information about it.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.89 FSTSYNC

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Fast Synchronization Mode condition occurs when the ONS 15600 synchronizes its clock modules. Since the ONS 15600 uses Stratum 3E timing, synchronization can take about 12 minutes. This condition occurs on the TSC card where the timing distribution is sourced. Whenever this condition is active, any timing or controller switching might affect the traffic. Errorless switching is not guaranteed.The "UNPROT-SYNCCLK" alarm on page 2-121 can accompany this condition if there is no timing protection is available while the clock is synchronizing.

If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.90 FULLPASSTHR-BI

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Bidirectional Full Pass-Through Active condition occurs on a nonswitching node in a BLSR when the protect channels on the node are active and carrying traffic and a change is present in the receive K byte from "No Request." (Both data and K bytes are in pass-through mode.)

Clear the FULLPASSTHR-BI Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

2.6.91 GFP-LFD

For information about this condition, refer to the "Alarm Troubleshooting" chapter of the Cisco ONS 15454 DWDM Troubleshooting Guide.

2.6.92 GFP-UP-MISMATCH

For information about this condition, refer to the "Alarm Troubleshooting" chapter of the Cisco ONS 15454 DWDM Troubleshooting Guide.

2.6.93 HELLO

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The Open Shortest Path First (OSPF) Hello Fail alarm occurs when SONET DCC termination OSPF area IDs are mismatched between two DCC terminations for a span. On a span between two ONS 15600s, this alarm occurs at both nodes containing the mismatched DCC area IDs. On a span between an ONS 15600 and an ONS 15454, this alarm is raised only on the ONS 15600 node. Mismatched OSPF area IDs can cause CTC to lose management across the link.

Clear the HELLO Alarm

Step 1 Log into both end nodes with the DCC terminations.

Step 2 On the nodes where the alarm occurred, record the slot and port (from the Slot column and Port column in the Alarms window) that the Hello alarm occurs against. This information helps you determine which DCC termination is mismatched.

Tip You can log into another node by going to network view and double-clicking the node.

2.6.97 HLDOVRSYNC

The Holdover Synchronization Mode condition is caused by loss of the primary and second timing references in the node. Timing reference loss occurs when line coding on the timing input is different from the configuration on the node, and it often occurs during the selection of a new node reference clock. The condition clears when primary or second timing is reestablished. After the 24-hour holdover period expires, timing slips could begin to occur on an ONS 15600 relying on an internal clock.

Step 2 Reestablish a primary and secondary timing source according to local site practice. If none exists, refer to the "Change Node Settings" chapter in the Cisco ONS 15600 Procedure Guideto find one.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) in order to report a Service-Affecting (SA) problem.

2.6.99 IMPROPRMVL (EQPT, PIM, PPM)

•A card is removed when the card was rebooting. It is recommended that after the card completely reboots, delete the card in CTC and only then remove the card physically. When you delete the card, CTC loses connection with the node view (single-shelf mode) or shelf view (multishelf mode), and goes to network view.

•When a card is physically removed from its slot before it is deleted from CTC. It is recommended that any card be deleted in CTC before physically removing the card from the chassis.

Note CTC provides the user approximately 15 seconds to physically remove the card before it begins rebooting the card.It can take up to 30 minutes for software to be updated on a standby TSC card.

•A card is inserted into a slot but is not fully plugged into the backplane.

•A PPM (SFP) is provisioned but the physical module is not inserted into the port, or if no PPM is inserted into the 4PIO (PIM).

•Electrical issues such as short circuit or failure of DC-DC conversion.

Clear the IMPROPRMVL (EQPT, PIM, PPM) Alarm

Step 1 In node view, right-click the card reporting the IMPROPRMVL.

Step 2 Choose Delete from the shortcut menu.

Note CTC does not allow you to delete the reporting card if the card is in service, does have circuits mapped to it, is paired in a working protection scheme, has DCC enabled, or is used as a timing reference. However if none of these services is provisioned, you can delete an IS card.

Step 3 If any ports on the card are in service, place them out of service (OOS,MT) by completing the following steps:

2.6.100 IMPROPRMVL (EQPT for the SSXC or TSC Card)

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: EQPT

The Improper Removal SSXC, Traffic Card, or TSC card alarm occurs when a TSC card, SSXC card, or traffic (OC-N) card is physically removed from its slot. This alarm can occur if the card is recognized by CTC and the active TSC card but is not in service. For example, it could be inserted in the slot but not fully plugged into the backplane.

If the removed TSC card or SSXC card is the last one on the shelf, the severity is Critical (CR) and traffic is affected. Otherwise, the alarm is Minor (MN).

Caution Do not remove and reinsert (reseat) a card during a card reboot. If CTC begins to reboot a card before you remove the card, allow the card to finish rebooting. After the card reboots, delete the card in CTC again and physically remove the card before it begins to reboot.

Note After deleting a card in CTC, the software allows you approximately 15 seconds to physically remove the card before CTC begins a card reboot.

Clear the IMPROPRMVL (SSXC, TSC) Alarm

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.102 IMPR-XC

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: NE

The Improper Cross-Connect Card alarm indicates that the CXC card is being used rather than the SSXC (the preferred cross-connect card for Software R5.0 and later). The alarm remains standing as long as a CXC is present on the node. Since a CXC card is still capable of passing traffic, the alarm is not Service-Affecting (SA). However, a system containing a CXC card and the current software release is not fully guaranteed for functionality.

Note IMPR-XC is an informational alarm and does not require troubleshooting. However, if you are experiencing cross-connect related problems at this site, also report this alarm to the Cisco TAC.

2.6.103 INCOMPATIBLE-SEND-PDIP

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: SYSTEM

The Incompatible Send-PDIP alarm is raised when CTC's send-PDIP provisioning differs from the host node's provisioning.

Logical Object: NE

The Security Intrusion Incorrect Password condition occurs after a user attempts a provisionable (by Superuser) number of unsuccessful logins, a login with an expired password, or an invalid password. The alarmed user is locked out of the system, and INTRUSION-PSWD condition is raised. This condition is only shown in Superuser login sessions, not in login sessions for lower-level users. The INTRUSION-PSWD condition is automatically cleared when a provisionable lockout timeout expires, or it can be manually cleared in CTC by the Superuser if lockout is permanent.

Clear the INTRUSION-PSWD Condition

Step 1 Click the Provisioning > Security > Users tabs.

Step 2 Click Clear Security Intrusion Alarm.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

Default Severity: Major (MJ), Non-Service-Affecting (NSA)

Logical Object: BPLANE

The Invalid MAC Address alarm occurs when the ONS 15600 MAC address retrieval fails and the node does not have a valid MAC address to support the operating system (OS). Do not attempt to troubleshoot an INVMACADR alarm. Contact the Cisco TAC at (1-800-553-2447).

Clear the INVMACADR Alarm

Step 1 Check for any outstanding alarms that were raised against the active and standby TSC and resolve them.

Step 2 At the earliest maintenance window, reset the standby TSC:

Note The reset requires approximately five minutes. Do not perform any other step until the reset is complete.

a. Log into a node on the network. If you are already logged in, continue with Step b.

b. Identify the active TSC.

A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.

c. Right-click the standby TSC.

d. Choose Reset Card from the shortcut menu.

e. Click Yes in the Are You Sure dialog box.

The card resets, the FAIL LED blinks on the physical card, and connection to the node is lost. CTC switches to network view.

f. Verify that the reset is complete and error-free, and that no new related alarms appear in CTC. A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.

g. Double-click the node and ensure that the reset TSC is still in standby mode and that the other TSC is active.

A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.

h. Ensure that no new alarms associated with this reset appear in the CTC Alarms window.

If the standby TSC fails to boot into standby mode, then open a case with Cisco TAC (1 800 553-2447) for assistance.

Note If the replacement TSC is loaded with a different software version from the current TSC, the card bootup could take up to 30 minutes. During this time, the card LEDs flicker between Fail and Act/Sby as the active TSC version software is copied to the new standby card.

Step 7 Open a case with Cisco TAC (1 800 553-2447) for assistance with determining the node's previous MAC address.

Step 8 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC 1 800 553-2447.

2.6.107 ISIS-ADJ-FAIL

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The Open System Interconnection (OSI) Intermediate System to Intermediate-System (IS-IS) Adjacency Failure alarm is raised by an intermediate system (node routing IS Level 1 or Level 1 and 2) when no IS or end system (ES) adjacency is established on a point-to-point subnet. The Intermediate-System Adjacency Failure alarm is not supported by ES. It is also not raised by IS for disabled routers.

The alarm is typically caused by a misconfigured router manual area adjacency (MAA) address. For more information about IS-IS OSI routing and MAA configuration, refer to the "Management Network Connectivity" chapter in the Cisco ONS 15600 Reference Manual. For more information about configuring OSI, refer to the "Turn Up Node" chapter in the Cisco ONS 15600 Procedure Guide.

Clear the ISIS-ADJ-FAIL Alarm

Step 1 Ensure that both ends of the comm channel are using the correct Layer 2 protocol and settings (LAPD or PPP). To do this, complete the following steps:

c. In the Edit SDCC termination dialog box, view and record the following selections: Layer 2 protocol (LAPD or PPP); Mode radio button selection (AITS or UITS); Role radio button selection (Network or User); MTU value; T200 value; and T203 selections.

d. Click Cancel.

e. Log in to the remote node and follow the same steps, also recording the same information for this node.

Step 2 If both nodes do not use the same Layer 2 settings, you will have to delete the incorrect termination and recreate it. To delete it, click the termination and click Delete. To recreate it, refer to the "Turn Up Node" chapter in the Cisco ONS 15600 Procedure Guide for the procedure.

Step 4 If both nodes use the LAPD Layer 2 protocol but have different Mode settings, change the incorrect node's entry by clicking the correct setting radio button in the Edit SDCC termination dialog box and clicking OK.

Step 5 If the Layer 2 protocol and Mode settings are correct, ensure that one node is using the Network role and the other has the User role. If not (that is, if both have the same mode settings), correct the incorrect one by clicking the correct radio button in the Edit SDCC termination dialog box and clicking OK.

Step 6 If the Layer 2, Mode, and Role settings are correct, compare the MTU settings for each node. If one is incorrect, choose the correct value in the Edit SDCC dialog box and click OK.

Step 7 If all of the preceding settings are correct, ensure that OSI routers are enabled for the communication channels at both ends by completing the following steps:

a. Click the Provisioning > OSI > Routers > Setup tabs.

b. View the router entry under the Status column. If the status is Enabled, check the other end.

c. If the Status is Disabled, click the router entry and click Edit.

d. Check the Enabled check box and click OK.

Step 8 If the routers on both ends are enabled and the alarm still has not cleared, ensure that both ends of the comm channel have a common MAA by completing the following steps:

a. Click the Provisioning > OSI > Routers > Setup tabs.

b. Record the primary MAA and secondary MAAs, if configured.

Tip You can record long strings of information such as the MAA address by using the CTC export and print functions. Export it by choosing File > Export > html. Print it by choosing File > Print.

c. Log into the other node and record the primary MAA and secondary MAAs, if configured.

d. Compare this information. There should be at least one common primary or secondary MAA in order to establish an adjacency.

e. If there is no common MAA, one must be added to establish an adjacency. Refer to the "Turn Up Node" chapter in the Cisco ONS 15600 Procedure Guide for instructions to do this.

Step 9 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.108 KB-PASSTHR

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The K Byte Pass Through Active condition occurs on a nonswitching node in a BLSR when the protect channels on the node are not active and the node is in K Byte pass-through state. It also occurs when a BLSR ring is being exercised using the Exercise Ring command.

Clear the KB-PASSTHR Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.109 KBYTE-APS-CHANNEL-FAILURE

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: OCN

The APS Channel Failure alarm is raised when a span is provisioned for different APS channels on each side. For example, the alarm is raised if K3 is selected on one end and F1, E2, or Z2 is selected on the other end.

This alarm is also raised during checksum failure if the K1 and K2 bytes are overwritten by test equipment. It is not raised in bidirectional full pass-through or K-byte pass-through states. The alarm is overridden by AIS-P, LOF, LOS, or SF-BER alarms.

Clear the KBYTE-APS-CHANNEL-FAILURE Alarm

Step 1 The alarm is most frequently raised due to mismatched span provisioning. In this case, reprovision one side of the span with the same parameters. To do this, refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guidefor procedures.

Step 3 If third-party equipment is involved, ensure that it is configured for the same APS channel as the Cisco ONS equipment.

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Lockout of Protection Span condition occurs on a BSLR node when traffic is locked out of a protect span using the LOCKOUT SPAN command. This condition is visible on the network view Alarms, Conditions, and History tabs after the lockout has occurred and accompanies the FE-LOCKOUTPR-SPAN condition. The port where the lockout originated is marked by an "L" on the network view detailed circuit map.

Clear the LKOUTPR-S Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.113 LOCKOUT-REQ

Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: OCN, STSMON

The Lockout Switch Request on Facility or Equipment condition occurs when a user initiates a lockout switch request for an OC-N port in a 1+1 facility protection group. This can be accomplished by locking traffic onto the working port with the Lock On command (thus locking it off the protect port), or locking it off the protect port with the Lock Out command. In either case, the protect port will show "Lockout of Protection," and the Conditions window will show the LOCKOUT-REQ condition.

Clear the LOCKOUT-REQ Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.115 LOF (BITS)

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: BITS

The Loss of Frame (BITS) alarm is Major (MJ) if there is no backup TSC card BITS source and Minor (MN) if one of the TSC cards BITS sources fails. If one of the pair fails, a timing APS is activated on the second source.

Clear the LOF (BITS) Alarm

Step 1 Verify that the framing and coding match between the BITS input and the TSC card by completing the following steps:

a. Find the coding and framing formats of the external BITS timing source. This should be in the user documentation for the external BITS timing source or on the external timing source itself.

b. Click the node view Provisioning > Timing > BITS Facilities tabs.

c. Verify that the Coding setting matches the Coding setting of the BITS timing source (either B8ZS or AMI).

d. If the coding does not match, click Coding to display a drop-down list. Choose the appropriate coding.

e. Verify that the Framing matches the framing of the BITS timing source (either ESF or SF [D4]).

f. If the framing does not match, click Framing to display the drop-down list. Choose the appropriate framing.

Note In the Timing window, the B8ZS coding field is normally paired with ESF in the Framing field, and the AMI coding field is normally paired with SF (D4) in the Framing field.

2.6.116 LOF (OCN)

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: OCN

The Line Loss of Frame Alignment alarm occurs when a port on the reporting traffic (OC-N) card has an LOF. LOF indicates that the receiving ONS 15600 has lost frame delineation in the incoming data and when the SONET overhead loses a valid framing pattern for three milliseconds. Receiving two consecutive valid A1/A2 framing patterns clears the alarm.

LOF on a traffic card is sometimes an indication that the port reporting the alarm expects a specific line rate and the input line rate source does not match the input line rate of the optical receiver.

If the port is in 1+1 protection and successfully switches, the alarm severity is MN, NSA. If the port is unprotected or if protection switching is prevented, the severity is CR, SA.

Clear the LOF (OCN) Alarm

Step 1 Verify that the automatic protection switch to the protect port was successful.

•A 1+1 APS is identified on the node view Maintenance > Protection tab. If you click the protection group, under the Selected Group list, the ports are designated as Working/Standby and Protect/Active.

Step 2 Verify that the traffic (OC-N) card and port on the upstream node is in service.

•On an in-service traffic card, the green SRV and Laser On LEDs are illuminated.

•If the card ports are in service, in the card view Provisioning tab, the Status column for the port(s) show In Service. If the ports are not in service, click the port column and choose In Service, then click Apply.

Step 3 If the alarm does not clear, clean the optical fiber connectors by completing the following steps:

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

a. Clean the fiber connectors according to local site practice.

b. If no local practice exists, use a CLETOP Real-Type or equivalent fiber-optic cleaner and follow the instructions accompanying the product and/or refer to the procedures in the "Maintain the Node" chapter in the Cisco ONS 15600 Procedure Guide.

2.6.117 LOGBUFR90

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: SYSTEM

The Log Buffer Over 90 alarm indicates that the per-NE queue of incoming alarm, event, or update capacity of 5,000 entries is over 90 percent full. LOGBUFR90 will clear if CTC recovers. If it does not clear, LOGBUFROVFL occurs.

Note LOGBUFR90 is an informational alarm and does not require troubleshooting.

2.6.118 LOGBUFROVFL

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: SYSTEM

The Log Buffer Overflow alarm indicates that the CTC per-NE queue of incoming alarm, event, or updates, which has a capacity of 5,000 entries, has overflowed. This happens only very rarely. However if it does, you must restart the CTC session. It is likely that some updates will have been missed if this alarm occurs.

Clear the LOGBUFROVFL Alarm

Step 1 Restart the CTC session.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1-800-553-2447).

2.6.119 LO-LASERBIAS

For information about this condition, refer to the "Alarm Troubleshooting" chapter of the Cisco ONS 15454 DWDM Troubleshooting Guide.

2.6.120 LOP-P

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: STSMON

A Loss of Pointer Path alarm indicates that the transmitted optical circuit size is different from the provisioned optical circuit size. LOP-P occurs when valid H1/H2 pointer bytes are missing from the SONET overhead. Receiving equipment monitors the H1/H2 pointer bytes to locate the SONET payload. An LOP-P alarm means that eight, nine, or ten consecutive frames do not have valid pointer values. The alarm clears when three consecutive valid pointers are received.

One of the conditions that can cause this alarm is a transmitted STSc circuit that is different from the provisioned STSc. This condition causes a mismatch of the path type on the concatenation facility. It occurs when there are eight to ten new data flags received, or eight to ten invalid pointers. For example, if an STS-3c or STS-1 is sent across a path provisioned for STS-12c, an LOP alarm occurs.

Clear the LOP-P Alarm

Step 2 Use a test set to verify that the incoming signal is valid; refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions on testing optical circuits. If the upstream signal is not valid, troubleshoot upstream.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Note If the traffic (OC-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port. Refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions. Label the bad port, and place it out of service until the card can be replaced.

Step 4 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

Clear the LOS (BITS) Alarm

Step 1 Check the wiring connection from the ONS 15600 backplane BITS clock pin fields to the timing source. For more information about backplane wiring connections, refer to the "Install the Bay and Backplane Connections" chapter in the Cisco ONS 15600 Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 Ensure that the BITS clock is operating properly.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

2.6.123 LOS (OCN)

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: OCN

A Loss of Signal Line alarm for either an OC-48 or OC-192 port occurs when the port on the card is in service but no signal is being received. The cabling might not be correctly connected to the ports, or no signal exists on the line. Possible causes for a loss of signal include upstream equipment failure or a fiber cut. It clears when two consecutive valid frames are received.

Clear the LOS (OCN) Alarm

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 If the cabling is good, verify that the correct port is in service by completing the following steps:

a. Confirm that the LED is correctly illuminated on the physical card.

A green SRV LED indicates an active card.

b. To determine whether the OC-N port is in service, double-click the card in CTC to display the card view by completing the following steps:

c. Click the Provisioning > Linetabs.

d. Verify that the Admin State column lists the port as IS.

e. If the Admin State column lists the port as OOS,MT or OOS,DSBLD, click the column and choose IS.

f. Click Apply.

Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is either raised or remains, and the port service state transitions to OOS-AU,FLT.

Step 3 If the correct port is in service, clean the fiber according to site practice. If no site practice exists, complete the procedure in the "Maintain the Node" chapter in the Cisco ONS 15600 Procedure Guide.

Step 5 If the optical power level is within specifications, use an optical test set to verify that a valid signal exists on the line. For specific procedures to use the test set equipment, consult the manufacturer. Test the line as close to the receiving card as possible.

Step 6 If a valid signal exists, replace the connector on the backplane.

Step 7 Repeat Steps 1 to 6 for any other port on the card reporting the LOS (OC-N).

Step 8 If the alarm does not clear, look for and troubleshoot any other alarm that could identify the source of the problem.

Step 9 If no other alarms exist that could be the source of the LOS, or if clearing an alarm did not clear the LOS, complete the "Replace an I/O Card" procedure for the reporting card.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Step 10 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) in order to report a Service-Affecting (SA) problem.

2.6.125 LPBKCRS

Default Severity: Not Alarmed (NA), Service-Affecting (SA)

Logical Object: STSMON

The Loopback Cross-Connect condition indicates that a software cross-connect loopback is active between a traffic (OC-N) card and a cross-connect card.

Loopback is a commonly used troubleshooting technique. A signal is sent out on a link or section of the network and returned to the sending device. If the signal does not return or returns with errors, the test confirms that the problem is present in the tested link. By setting up loopbacks on various parts of the node and excluding other parts, you can logically isolate the source of the problem. For more information about loopbacks, see the "Troubleshooting Optical Circuits with Loopbacks" procedure in Chapter 1.

Four types of loopbacks are available: Cross-Connect, Facility, Terminal, and Payload. Cross-connect loopbacks troubleshoot any kind of STS (meaning there must be a cross connect) on any card type. Facility loopbacks troubleshoot OC-48-16 and ASAP ports only and are generally performed locally or at the near end. Payload loopbacks troubleshoot OC-192-4 ports only and are generally performed locally or at the near end. Terminal loopbacks are performed only on the ASAP card.

Clear the LPBKFACILITY (GIGE) Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.143 MFGMEM (CAP)

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: CAP

The Manufacturing Data Memory Failure CAP alarm occurs if the ONS 15600 cannot access the data in the EEPROM on the backplane. MFGMEM is caused by EEPROM failure on the backplane, or fuse failure for the EEPROM.

The EEPROM stores manufacturing data that is needed for compatibility and inventory issues. If the alarm is accompanied by the "PWR-FA" alarm on page 2-102, the 5-VDC fuse for the EEPROM might be tripped. If that is the case, use the procedure below to eliminate the TSC card as the cause of the alarm, but do not attempt to troubleshoot it further. Contact the Cisco TAC at 1-800-553-2447.

If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447). The standby TSC card might also need replacement. If the alarm continues after both TSC cards have been replaced, the problem lies in the EEPROM on the CAP, and this must be replaced.

2.6.144 MFGMEM (FAN)

The Manufacturing Data Memory Fan alarm occurs if the ONS 15600 EEPROM on a fan tray fails. MFGMEM can be accompanied by the "FAN-FAIL" alarm on page 2-59.

Logical Objects: EQPT, PIM, PPM

The Manufacturing Data Memory Failure SSXC, Traffic (OC-N), or TSC Card alarm occurs if the ONS 15600 EEPROM on one of these cards fails.

Step 2 If the reporting card is an active traffic line port in a 1+1 protection group or a path protection, ensure that an APS traffic switch has occurred to move traffic to the protect port.

•A path protection APS is identified by an AUTOSW-type alarm or condition (such as AUTOSW-AIS, AUTOSW-PDI, AUTOSW-SDBER, AUTOSW-SFBER, or AUTOSW-UNEQ).

•A 1+1 APS is identified on the node view Maintenance > Protection tab. If you click the protection group, under the Selected Group list, the ports are designated as Working/Standby and Protect/Active.

Note If the traffic (OC-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using the "Bridge and Roll Traffic" procedure in the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide. Label the bad port, and place it out of service until such time as the card can be replaced.

Step 7 If the MFGMEM alarm continues to report after you replaced the card, the problem lies in the EEPROM. Log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.146 NOT-AUTHENTICATED

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: SYSTEM

The NOT-AUTHENTICATED alarm is raised by CTC (not by the NE) when it fails to log into a node. This alarm only displays in CTC where the login failure occurred. This alarm differs from the "INTRUSION-PSWD" alarm on page 2-76 in that INTRUSION-PSWD occurs when a user exceeds the login failures threshold.

Note NOT-AUTHENTICATED is an informational alarm and is resolved when CTC successfully logs into the node.

2.6.147 OPEN-SLOT

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

The OPEN-SLOT alarm indicates that one of the I/O slots (Slot 1 through 4 and 11 through 14) does not contain a traffic card or filler card.

Clear the OPEN-SLOT Alarm

Step 1 Insert a filler card or OC-N card into the empty slot.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.148 PDI-P

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: STSMON

A Payload Defect Indication Path condition indicates that a signal label mismatch failure (SLMF) in the STS-1 signal. An invalid C2 byte in the SONET path overhead causes an SLMF. The C2 byte is the signal-label byte that tells the equipment what the SONET payload envelope contains and how it is constructed. It enables a SONET device to transport multiple types of services.

The ONS 15600 encounters an SLMF when the payload, such as an asynchronous transport mode (ATM), does not match what the signal label is reporting. The "AIS-P" condition on page 2-17 often accompanies the PDI-P alarm. If the PDI-P is the only alarm reported with an AIS-P, clear the PDI-P alarm to clear the AIS-P alarm. PDI-P can also occur during an upgrade, but usually clears itself and is not a valid alarm.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Clear the PDI-P Condition

Step 1 Check the incoming signal overhead with an optical test to verify that the C2 byte is correct. Refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guide for circuit test procedures.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 If the C2 byte is not correct, it indicates an upstream equipment problem (typically with path-terminating equipment [PTE]). Troubleshoot the upstream equipment.

Note If the traffic (OC-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port; refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions. Label the bad port and place it out of service until the card can be replaced.

Step 4 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.149 PLM-P

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: STSMON

A Payload Label Mismatch Path alarm indicates that signal does not match its label. The condition is indicated by a problematic C2 byte value in the SONET path overhead. The alarm is raised if all of the following conditions are met:

•The received C2 byte is not 0x00 (unequipped).

•The received C2 byte is not a PDI value.

•The received C2 does not match the expected C2.

•The expected C2 byte is not 0x01 (equipped, unspecified).

•The received C2 byte is not 0x01 (equipped, unspecified).

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Clear the PLM-P Alarm

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) in order to report a Service-Affecting (SA) problem.

2.6.150 PRC-DUPID

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: OCN

The Procedural Error Duplicate Node ID alarm indicates that two identical node IDs exist in the same BLSR. The ONS 15600 requires each node in the BLSR to have a unique node ID.

Step 3 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.152 PWR

Default Severity: Major (MJ), Non-Service Affecting (NSA)

Logical Object: PWR

The NE Power Failure at Connector alarm occurs when one of the two power supplies (A or B) is not detected. This could be because the supply is removed or is not operational. The alarm does not distinguish between the individual power supplies, so onsite information about the alarm is necessary for troubleshooting.

Effects of this alarm depend upon the shutdown order of the two power supplies. If PWR B of the right-side power feed and PWR A of the left-side power feed are shut down, this causes all three fans to turn off and a "FAN-FAIL" alarm on page 2-59 to be raised. In this case, after power is restored all three fans work in high-speed mode for a few minutes until CTC returns them to normal speed. All alarms are cleared.

Clear the PWR Alarm

Step 1 At the site, determine which battery is not present or operational.

Step 2 Remove the power cable from the faulty supply. For instructions, refer to the "Install the Bay and Backplane Cable" chapter in the Cisco ONS 15600 Procedure Guide and reverse the power cable installation procedure.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.153 PWR-FA

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: BPlane

The Backplane Power Fuse Failure alarm indicates that the backplane EEPROM memory 5-VDC fuse fails, but the equipment is still in service. Service is not currently affected, but network management can be affected because the ONS 15600 system uses a default NE (node) IP address instead of a programmed one in this case. This alarm might be accompanied by the "INVMACADR" alarm on page 2-76, which appears in the alarm history when network management capability is restored.

Do not attempt to troubleshoot the alarm. If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.154 PWR-FAIL-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Objects: CAP, EQPT

The Equipment Power Failure at Connector A alarm occurs when there is no power supply from the main power connector to the equipment. This alarm occurs on the CAP, SSXC card, traffic (OC-N) cards, or TSC card.

Warning The power supply circuitry for the equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the DSLAM equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment. Statement 207

Clear the PWR-FAIL-A Alarm

Step 1 If a single card has reported the alarm, take one of the following actions depending what kind of card reported it:

•If the reporting card is an active traffic line port in a 1+1 protection group or part of a path protection, ensure that an APS traffic switch has occurred to move traffic to the protect port.

–A path protection APS is identified by an AUTOSW-type alarm or condition (such as AUTOSW-AIS, AUTOSW-PDI, AUTOSW-SDBER, AUTOSW-SFBER, or AUTOSW-UNEQ).

–A 1+1 APS is identified on the node view Maintenance > Protection tab. If you click the protection group, under the Selected Group list, the ports are designated as Working/Standby and Protect/Active.

To determine which SSXC card is the preferred copy and if it is currently being used, open the node view Maintenance > Preferred Copy window. The Data Copy area Preferred field shows Copy A or Copy B. The Currently Used field shows the copy being used.

Note In CTC, Copy A refers to the SSXC card in Slot 6/7. Copy B refers to the SSXC card in Slot 8/9. Either copy might be chosen as the preferred copy SSXC card. The other SSXC card is called the alternate SSXC card in this chapter.

Step 6 If the single card reseat and replacement does not clear the alarm, or if multiple cards report the alarm, verify the office power; refer to the "Install the Bay and Backplane Connections" chapter in the Cisco ONS 15600 Procedure Guide for power installation instructions.

Step 7 If the alarm does not clear, reseat the power cable connection to the connector. For more information about ONS 15600 power connections, refer to the "Install the Bay and Backplane Connections" chapter in the Cisco ONS 15600 Procedure Guide.

Step 8 If the alarm does not clear, physically replace the power cable connection to the connector.

Step 9 If the alarm does not clear, a problem with the power distribution unit (PDU) is indicated and it could need to be replaced. Complete the procedure located in the "Maintain the Node" chapter in the Cisco ONS 15600 Procedure Guide.

Step 10 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.155 PWR-FAIL-B

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Objects: CAP, EQPT

The Equipment Power Failure at Connector B alarm occurs when there is no power supplied to the backup power connector on the shelf. This alarm occurs on the CAP, SSXC card, traffic (OC-N) cards, or TSC card.

2.6.156 PWR-FAIL-RET-A

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Equipment Power Failure at Power Return A alarm occurs when the main power return path is not available. This alarm occurs on the TSC card, SSXC card, or traffic (OC-N) cards. Troubleshoot using the "Clear the PWR-FAIL-A Alarm" procedure.

2.6.157 PWR-FAIL-RET-B

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Equipment Power Failure at Power Return B alarm occurs when the main power return path is not available. This alarm occurs on the TSC card, SSXC card, or traffic (OC-N) cards.

2.6.158 PWRRESTART

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Power-Up Restart condition occurs when the shelf is restarted while no CTC connection is present. The Slot 5 TSC card on the shelf does not report this condition because the card is inactive when the condition occurs. You can see this condition in the Alarm History window when the CTC connection resumes.

2.6.159 RFI-L

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

Logical Object: OCN

An RFI Line condition occurs when the ONS 15600 detects an RFI in the SONET overhead of OC-48 and OC-192 cards because of a fault in another node. Resolving the fault in the adjoining node clears the RFI-L alarm in the reporting node.

RFI-L indicates that the alarm is occurring at the line level. The line layer is the segment between two SONET devices in the circuit and is also known as a maintenance span. The line layer deals with SONET payload transport. The line layer functions include multiplexing and synchronization.

Step 4 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.160 RFI-P

Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)

Logical Object: STSMON

An RFI Path condition occurs when the ONS 15600 detects an RFI in the SONET overhead of the STS-1 signal because of a fault in another node. Resolving the fault in the adjoining node clears the RFI-P alarm in the reporting node.

RFI-P occurs in the node that terminates a path. The path layer is the segment between the originating equipment and the terminating equipment. This segment might encompass several consecutive line segments. An RFI-P error message on theONS 15600 indicates that the node reporting the RFI-P is the terminating node on that path segment.

Clear the RFI-P Condition

Step 1 Verify that the ports are enabled and in-service on the reporting ONS 15600.

In the card-level view, traffic port state is indicated by the color of the port:

•Gray—Out of service (OOS)

•Green—In service (IS)

•Red—Critical (CR) alarm

•Yellow—Minor (MN) alarm

•Orange—Major (MJ) alarm

Step 2 If a port is OOS, click the Provisioning > Linetabs and choose In Service from the drop-down list for that port. Click Apply.

Step 3 To find the path and node failure, verify the integrity of the SONET circuit path at each of the intermediate SONET nodes, checking for inconsistencies in path size or protection configuration.

Step 4 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.162 RING-SW-EAST

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Ring Switch Is Active East Side condition occurs when a ring switch occurs at the east side of a BLSR using a Force Ring command. The condition clears when the switch is cleared. RING-SW-EAST is visible on the network view Alarms, Conditions, and History tabs. The port where the Force Ring was applied shows an "F" on the network view detailed circuit map.

Note RING-SW-EAST is an informational condition and does not require troubleshooting.

2.6.163 RING-SW-WEST

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Ring Switch Is Active West Side condition occurs when a ring switch occurs at the west side of a BLSR using a Force Ring command. The condition clears when the switch is cleared. RING-SW-WEST is visible on the network view Alarms, Conditions, and History tabs. The port where the Force Ring was applied shows an "F" on the network view detailed circuit map.

Note RING-SW-WEST is an informational condition and does not require troubleshooting.

2.6.164 ROLL

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: STSMON

The ROLL condition indicates that circuits are being rolled. This is typically carried out to move traffic for a maintenance operation or to perform bandwidth grooming. The condition indicates that a good signal has been received on the roll destination leg, but the roll origination leg has not yet been dropped. The condition clears when the roll origination leg is dropped.

Note ROLL is an informational condition and does not require troubleshooting.

2.6.165 ROLL-PEND

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: STSMON

ROLL-PEND indicates that a roll process has been started, but a good signal has not been received yet by the roll destination leg. This condition can be raised individually by each path in a bulk circuit roll.

The condition clears when a good signal has been received on the roll destination leg.

Note ROLL-PEND is an informational condition and does not require troubleshooting.

2.6.166 SD-L

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

A Signal Degrade Line condition occurs for an optical port that detects a signal degrade condition. Signal degrade is defined by Telcordia as a "soft failure" condition. SD-L and the SF-L condition (see the "SF-L" condition on page 2-109) monitor the incoming BER and are similar. SD is triggered at a lower bit error rate than SF.

The BER threshold on the ONS 15600 is user-provisionable and has a range for SD from 1E-9 dBm to 1E-5 dBm.

SD-L causes a switch from the working card to the protect card at the line (facility) level. A line- or facility-level SD alarm travels on the B2 byte of the SONET overhead.

The SD condition clears when the BER level falls to one tenth of the threshold level that triggered the alarm. A BER increase is sometimes caused by a physical fiber problem, including a faulty or incorrectly plugged fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.

Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm could pose an eye hazard. Statement 1056

Warning Use of controls, adjustments, or performing procedures other than those specified may result in hazardous radiation exposure. Statement 1057

Clear the SD-L Condition

Step 1 Verify that the user-provisionable BER threshold is set at the expected level by completing the following steps:

a. From node view, double-click the card reporting the alarm to display the card view.

b. Click the Provisioning > Line tabs.

c. Under the SD BER column in the Provisioning window, verify that the cell entry is consistent with what the system was originally provisioned for. The default setting is 1E-7 dBm.

d. If the entry is consistent with what the system was originally provisioned for, continue with Step 2.

e. If the entry is not consistent the original provisioning, click the cell to display a drop-down list of choices and choose the entry consistent with the original provisioning.

f. Click Apply.

Step 2 Ensure that the fiber connector for the card is completely plugged in. For more information about fiber connections and card insertion, refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

Step 3 Use an optical test set to measure the power level of the line to ensure it is within guidelines. Refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guidefor circuit test procedures.

Step 4 Verify that optical receive levels are within the acceptable range.

Step 5 Clean the fiber connectors at both ends for a line signal degrade by completing the following steps:

a. Clean the fiber connectors according to local site practice.

b. If no local practice exists, use a CLETOP Real-Type, 3M OGI connector cleaner, or equivalent fiber-optic cleaner and follow the instructions accompanying the product and/or refer to the procedures in the "Maintain the Node" chapter in the Cisco ONS 15600 Procedure Guide.

Step 6 Clean the optical transmitter and receiver by following site practice.

Note If the traffic card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using procedures in the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide. Label the bad port, and place it out of service until such time as the card can be replaced.

2.6.168 SF-L

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

A Signal Fail Line condition occurs when the quality of the signal on OC-48 and OC-192 cards causes the BER on the incoming optical line to exceed the SF threshold. Signal failure is defined by Telcordia as a "hard failure" condition. SD and SF both monitor the incoming BER error rate and are similar, but SF is triggered at a higher BER than SD. The default value of NA is determined by Telcordia GR-253-CORE.

The BER threshold on the ONS 15600 is user-provisionable and has a range for SF from 1E-5 dBm to 1E-3 dBm.

SF-L causes a switch from the working port to the protect port at the line (facility) level. A line or facility level SF condition travels on the B2 byte of the SONET overhead. The SF clears when the BER level falls to one-tenth of the threshold level that triggered the alarm. A BER increase is sometimes caused by a physical fiber problem, including a poor fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice. Troubleshoot with the "Clear the SD-L Condition" procedure.

2.6.170 SFTWDOWN

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

Note It takes approximately 20 minutes for the active TSC card to transfer the system software to the newly installed TSC card. Software transfer occurs in instances where different software versions exist on the two cards. When the transfer completes, the TSC card reboots and goes into standby mode after approximately three minutes.

Note If the active and standby TSC cards have the same versions of software, it takes approximately three minutes for software to be updated on a standby TSC card.

2.6.171 SNTP-HOST

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: NE

The Simple Network Timing Protocol (SNTP) Host Failure alarm indicates that an ONS node serving as an IP proxy for the other ONS nodes in the ring is not forwarding SNTP information to the other ONS nodes in the network. The forwarding failure can result from two causes, either the IP network attached to the ONS proxy node is experiencing problems, or the ONS proxy node itself is not functioning properly.

Clear the SNTP-HOST Alarm

Step 1 Ping the SNTP host from a workstation in the same subnet to ensure that communication is possible within the subnet by completing the "Ping the ONS 15600" procedure.

Step 2 If the ping fails, contact the network administrator who manages the IP network that supplies the SNTP information to the proxy and determine whether the network is experiencing problems which might affect the SNTP server/router connecting to the proxy ONS 15600.

Step 3 If no network problems exist, ensure that the ONS 15600 proxy is provisioned correctly by completing the following steps:

a. In node view for the ONS node serving as the proxy, click the Provisioning > General tabs.

b. Ensure that theUse NTP/SNTP Server check box is checked.

c. If the Use NTP/SNTP Server check box is not checked, click it.

2.6.174 SSM-DUS

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: BITS, OCN

The Synchronization Status Messaging (SSM) Changed to Do Not Use (DUS) condition occurs when the synchronization status message quality level changes to DUS.

The port that reports the condition is not at fault. The condition applies to the timing source. SSM-DUS prevents timing loops by providing a termination point for the signal usage.

2.6.175 SSM-FAIL

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Objects: BITS, OCN

The SSM Failed to Receive Synchronization alarm occurs when SSM received by the ONS 15600 fails. The problem is external to the ONS 15600. If one of two sources fails, the alarm is Minor (MN). If there is no backup source, the alarm is Major (MJ). This alarm indicates that although the ONS 15600 is set up to receive SSM, the timing source is not delivering valid SSM messages.

Clear the SSM-FAIL Alarm

Step 1 Verify that SSM is enabled on the external timing source.

Step 2 Use an optical test set to determine whether the external timing source is delivering SSM; refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guide for circuit test procedures.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.176 SSM-OFF

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: BITS, OCN

The SSM Changed to Off condition occurs when SSM is disabled by a user.

SSM communicates information about the quality of the timing source. SSM is carried on the S1 byte of the SONET line layer. It enables SONET devices to automatically select the highest quality timing reference and to avoid timing loops. Troubleshoot with the "Clear the SSM-FAIL Alarm" procedure if desired.

2.6.184 SSM-STU

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: BITS, NE-SREF, OCN

The SSM Synchronization Traceability Unknown condition occurs when the reporting node is timed to a reference that does not support SSM, but the ONS 15600 has SSM support enabled. SSM-STU can also be raised if the timing source is sending out SSM messages but SSM is not enabled on the ONS 15600.

2.6.186 STS-SQUELCH-L

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: OCN

The Ring is Squelching STS traffic condition is raised on an OC-N facility. If the node failure scenario includes the source or destination node, then switching nodes squelches all the STSs that originate from or terminate at the failure node. The condition resolves when the node is no longer failing.

This condition is raised as NA severity by default. However, it indicates that traffic is squelched due to node failure, that is, traffic outage. Traffic outage can be caused by different problems, such as multiple LOS alarms, AIS-L, or node power outage. STS-SQUELCH-L is symptomatic and indicates that the user must investigate which node in a ring is being isolated and what causes node isolation.

Note STS-SQUELCH-L is an informational condition.

2.6.187 SWTOPRI

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: EXT-SREF, NE-SREF

The Synchronization Switched to Primary Reference condition occurs when the ONS 15600 switches to the primary timing source (reference 1). The ONS 15600 uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference.

2.6.188 SWTOSEC

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: EXT-SREF, NE-SREF

The Synchronization Switched to Second Reference condition occurs when the ONS 15600 has switched to a second timing source (reference 2). To clear the SWTOSEC condition, complete the "Clear the SYNCPRI Alarm" procedure.

2.6.189 SWTOTHIRD

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: EXT-SREF, NE-SREF

The Synchronization Switched to Third Reference condition occurs when the ONS 15600 has switched to a third timing source (reference 3). To clear the SWTOTHIRD condition, complete the "Clear the SYNCPRI Alarm" procedure.

2.6.190 SW-VER

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: EQPT

The Software Version condition is reported when a new software version is activated on the ONS 15600. When a new version of software is uploaded, it results in the active TSC card running the new version and the standby TSC card running the old version. This situation raises the SW-VER condition. It remains until the user accepts the new version in the CTC. The acceptance causes the standby TSC card to reboot and upload the new version.

If the user does not accept the version, the active TSC card switches to the standby TSC card with the original version. After the switch, the new standby TSC card reverts to the previous version.

Note It takes approximately 20 minutes for the active TSC card to transfer the system software to the newly installed TSC card. Software transfer occurs in instances where different software versions exist on the two cards. When the transfer completes, the TSC card reboots and goes into standby mode after approximately three minutes.

Note If the active and standby TSC cards have the same versions of software, it takes approximately three minutes for software to be updated on a standby TSC card.

Step 4 If the SYNC-FREQ alarm continues to report after replacing the TSC card, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.193 SYNCPRI

A Primary Synchronization Reference Failure alarm occurs at the NE (node) level when the ONS 15600 loses the primary timing source (reference 1). The ONS 15600 uses three ranked timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCPRI occurs, the ONS 15600 should switch to its second timing source (reference 2). This switch also triggers the SWTOSEC alarm.

Clear the SYNCPRI Alarm

Step 1 From node view, click the Provisioning > Timing > General tabs and identify the timing source in REF-1 of the NE Reference.

Step 2 If REF-1 is Internal, this refers to the active TSC card. Look for any alarms related to the TSC card and troubleshoot them.

Step 5 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.194 SYNCSEC

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Objects: EXT-SREF, NE-SREF

A Second Synchronization Reference Failure Alarm occurs at the NE (node) level when the ONS 15600 loses the second timing source (reference 2). If SYNCSEC occurs, the ONS 15600 should switch to a third timing source (reference 3) to obtain valid timing for the ONS 15600. This switch also triggers the "SWTOTHIRD" condition on page 2-115.

Step 5 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.195 SYNCTHIRD

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: EXT-SREF

A Loss of Timing on Third Reference alarm occurs when the ONS 15600 loses the third timing source (reference 3). If SYNCTHIRD occurs and the ONS 15600 uses an internal reference for source three, the TSC card might have failed. The ONS 15600 often reports either the "FRNGSYNC" alarm on page 2-68 or the "HLDOVRSYNC" condition on page 2-71 after a SYNCTHIRD alarm.

Clear the SYNCTHIRD Alarm

Step 1 In node view, click the Provisioning > Timing > General tabs.

Step 2 Verify that the current configuration of REF-3 for the NE Reference. For more information about references, refer to the "Change Node Settings" chapter in the Cisco ONS 15600 Procedure Guide.

Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15600. Plug the wristband cable into the ESD jack located on the lower-right edge of the shelf assembly.

2.6.196 SYSBOOT

Default Severity: Major (MJ), Service-Affecting (SA)

Logical Object: NE

The System Reboot alarm indicates that new software is booting on the node or shelf TSC card. No action is required. The alarm clears when all cards finish rebooting the new software. The reboot takes approximately three minutes.

2.6.197 TIM-P

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: STSMON

The STS TIM-P alarm occurs when the current expected STS-1 path trace string does not match the current received path trace string. Path Trace Mode must be set to manual for this alarm to occur.

In manual mode in the Path Trace area, the user can type a new expected string into the field. This string must match the string typed into the Current Received String field for the sending port. If these fields do not match, it is typically because of upstream PTE error.

Clear the TIM-P Alarm

Step 1 Log into CTC at the circuit source and note which slot and port is reporting the alarm in the Alarms window.

Step 2 Click the Circuits > Circuits tabs.

Step 3 Select the circuit reporting the alarm by identifying it according to its Source or Destination column slots and ports. This circuit has probably switched to the protect port.

Step 7 Compare the Current Received String and Current Expected String entries in the path trace dialog box.

Step 8 If the strings differ and the Current Received String is correct but the Current Expected String is not, correct the Transmit or Expected strings and click Apply.

Step 9 If the strings differ and the Current Expected String is correct but the Current Received String is not, there is a problem with the PTE upstream. Troubleshoot the problem in the PTE.

Step 10 Click Close.

Step 11 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.198 TPTFAIL (POS)

The TPTFAIL alarm for packet over SONET (POS) is not used in this platform in this release. It is reserved for development.

2.6.199 UNEQ-P

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: STSMON

An SLMF Unequipped Path Signal Label Mismatch Failure alarm occurs when the path does not have a valid sender. The indicator is carried in the C2 signal path byte in the SONET overhead. The source of the problem is the node that is transmitting the signal into the node reporting the UNEQ-P.

UNEQ-P occurs in the node that terminates a path. The path layer is the segment between the originating equipment and the terminating equipment. This segment can encompass several consecutive line segments.

An UNEQ-P error message on the ONS 15600 indicates that the node reporting the "RFI-P" condition on page 2-105 is the terminating node on that path segment.

Note If you have created a new path but it has no signal, an UNEQ-P alarm is reported on the traffic (OC-N) cards and an AIS-P alarm is reported on the terminating cards. These alarms clear when the path carries a signal.

Clear the UNEQ-P Alarm

Step 1 From node view, navigate to the Circuits > Circuits tabs.

Under the State column, check for any circuit that has the status INCOMPLETE. (A completed circuit has ACTIVE status.)

Note Circuits have an incomplete status while they are in the process of being routed on the system. If you have created a large number of circuits, this status can remain for several minutes before it changes to active.

Step 2 If the alarm remains for some time and the circuit does not clear the alarm, delete the circuit by completing the following steps:

a. Click the incomplete circuit to highlight it.

b. Click Delete.

Step 3 Recreate the circuit as necessary; refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guide for instructions.

Step 4 If the alarm does not clear after re-creation, ensure that the circuit continues to pass traffic using an optical test set; refer to the "Create Circuits" chapter in the Cisco ONS 15600 Procedure Guide for circuit test procedures.

Step 5 If the alarm does not clear, verify that the incoming signal is valid by testing with an optical test set.

Step 6 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447) to report a Service-Affecting (SA) problem.

2.6.200 UNPROT-SYNCCLK

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: NE

The Unprotected Synchronization or Clock Equipment alarm indicates that only one TSC card has acquired the primary timing reference. The alarm is reported if there is no standby TSC card, or if the standby TSC card has restarted and 700 seconds (in FSTSYNC mode) have not elapsed.

This condition is normal following a change to the system timing reference (such as BITS to Line or Line to BITS). Changing the clock reference causes both TSC cards to raise the "FSTSYNC" condition on page 2-69, for 700 seconds. The UNPROT-SYNCCLK alarm occurs during this period. If both TSC cards are reset within 700 seconds of each other, this alarm occurs also and remains until both TSC cards attains the clock reference. If the alarm does not clear, follow the "Clear the UNPROT-SYNCCLK Alarm" procedure.

Clear the UNPROT-SYNCCLK Alarm

Step 1 Determine whether one or both TSC cards have the "FSTSYNC" condition on page 2-69 raised. If either TSC card has a FSTSYNC condition, wait 700 seconds for the condition and the UNPROT-SYNCCLK alarm to clear.

Step 2 If FSTSYNC was reported and continues after 700 seconds, replace the standby TSC card. Continue with Step 7.

Step 3 If FSTSYNC is not reported, from node view, click the Provisioning > Timing > General tabs.

Step 4 Verify the current configuration for REF-1 of the NE Reference.

Note It takes approximately 20 minutes for the active TSC card to transfer the system software to the newly installed TSC card. Software transfer occurs in instances where different software versions exist on the two cards. When the transfer completes, the TSC card reboots and goes into standby mode after approximately three minutes.

Note If the active and standby TSC cards have the same versions of software, it takes approximately three minutes for software to be updated on a standby TSC card.

Clear the UNPROT-XCMTX Alarm

Step 2 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.202 UNROUTEABLE-IP

Default Severity: Minor (MN), Non-Service-Affecting (NSA)

Logical Object: NE

The Illegal Route Addition to Network alarm is raised against the TSC card when it learns a route whose destination or next hop is on an internal subnet, or which is added over an incorrect interface. Such routes are learned by the OSPF protocol over the DCC links.

For example, in a mixed network of ONS 15454s and ONS 15600s, it is possible to provision the ONS 15600s with an internal subnet of 10.7.0.0 and, at the same time, provision one or more ONS 15454s with addresses on the same subnet. This situation raises the UNROUTEABLE-IP alarm because the ONS 15454s are considered to have bad addresses.You will not be able to communicate with them from the ONS 15600 nodes.

In some network configurations, all nodes and all DCC links will be displayed, but the ONS 15600s will appear uninitialized when viewed from the ONS 15454 network view, and the ONS 15454s will appear uninitialized when viewed from the ONS 15600 network view.

Note The ONS 15600 will not create a DCC connection to a neighboring ONS 15454 if the ONS 15454 has a bad IP address. The UNROUTEABLE-IP alarm will not be raised, but the "EOC" alarm on page 2-42 will be raised on both nodes.

Note It is possible to reuse an IP address on separate rings, but this is not recommended practice if traffic can be routed between the rings.

The UNROUTEABLE-IP alarm can be cleared in two ways. The internal subnet of the ONS 15600s can be changed to a subnet that is unused in the DCC network or the DCN. Alternately, the IP addresses of the ONS 15454s can be moved to a subnet outside of the ONS 15600 internal subnets.

Note To manage an ONS 15454 with a bad IP address, it is necessary to launch CTC from another ONS 15454. Likewise, to manage an ONS 15600, it is necessary to launch CTC from the an ONS 15600 or from an ONS 15454 that has a good IP address.

Clear the UNROUTEABLE-IP Alarm

Step 1 If you want to change the ONS 15454 subnet IP address, complete the following steps:

a. Log into the uninitialized ONS 15454 node.

b. In node view, click the Provisioning > Network > General tabs.

c. In the IP Address field, change the IP address to a unique number on the same subnet as the other, already initialized ONS 15454 nodes.

d. Click Apply.

e. Repeat for all uninitialized ONS 15454 nodes.

Step 2 If you want to change the ONS 15600 subnet IP dress instead, complete the following steps:

a. Log into the uninitialized ONS 15600 node.

b. In node view, click the Provisioning > Network > General tabs.

c. In the IP Address field, change the IP address to a unique number on the same subnet as the other, already initialized ONS 15600 nodes.

d. Click Apply.

Step 3 If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.203 UPGRADE

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Object: NE

The System Upgrade in Progress condition indicates that a system upgrade is occurring on the TSC card.

When software is downloaded, it is loaded into the available code volume on the active TSC card. The software is copied to the available code volume on the standby TSC card next. The "SFTWDOWN" condition on page 2-110 occurs at that time. When the user activates the load, the UPGRADE condition occurs.

Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the timing source because the Stratum 3E timing module is being adopted.

Clear the WKSWPR Condition

Step 2 If the condition does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport for more information or call Cisco TAC (1 800 553-2447).

2.6.205 WTR

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

Logical Objects: OCN, STSMON

The Wait to Restore condition indicates that revertive switching is specified and that a switch to protection occurred. When the working path is viable, this condition occurs while the wait to restore timer has not expired. The condition clears when the timer expires and traffic switches back to the working path.

2.6.206 XCMTX

Default Severity: Critical (CR), Service-Affecting (SA)

Logical Object: NE

The Unavailable Cross-Connection Matrix Equipment alarm indicates no cross-connection matrix on the NE (node). If there was previously a single SSXC card running in unprotected mode, that card fails. If there were two cards running in protected mode, the matrix has become unavailable on both. Troubleshoot with the "Clear the UNPROT-XCMTX Alarm" procedure.

2.7 LED Behavior

The following the subsections describe LED behaviors of the TSC card, SSXC card, and OC-N cards.

2.8 Frequently Used Alarm Troubleshooting Procedures

This section gives common procedures that are frequently used when troubleshooting alarms. Most of these procedures are summarized versions of more detailed procedures in the Cisco ONS 15600 Procedure Guide.

Note A Force command switches traffic on a working path even if the path has signal degrade (SD) or signal fail (SF) conditions. A Force switch does not switch traffic on a protect path. A Force switch preempts a Manual switch.

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Groups area, select the protection group with the port you want to switch.

Step 3 In the Selected Groups area, select the port belonging to the card you are replacing. You can carry out this command for the working or protect port. For example, if you need to replace the card with the Protect/Standby port, click this port.

Step 4 In the Switch Commands area, click Force.

Step 5 Click Yes in the Confirm Force Operation dialog box.

Step 6 If the switch is successful, the group says "Force to working" in the Selected Groups area.

Initiate a 1+1 Protection Port Manual Switch Command

This procedure switches 1+1 protection group traffic from one port in the group to the other using a Manual switch.

Note A Manual command switches traffic if the path has an error rate less than the signal degrade. A Manual switch is preempted by a Force switch.

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Groups area, select the protection group with the port you want to switch.

Step 3 In the Selected Groups area, select the port belonging to the card you are replacing. You can carry out this command for the working or protect port. For example, if you need to replace the card with the protect/standby port, click this port.

Step 4 In the Switch Commands area, click Manual.

Step 5 Click Yes in the Confirm Force Operation dialog box.

Step 6 If the switch is successful, the group now says "Manual to working" in the Selected Groups area.

Clear a 1+1 Protection Port Force or Manual Switch Command

Note If the 1+1 protection group is configured as revertive, clearing a Force switch to protect (or working) moves traffic back to the working port. In revertive operation, the traffic always switches back to working. There is no revert to protect. If ports are not configured as revertive, clearing a Force switch to protect does not move traffic back.

Note If the Force Switch was user-initiated, the reversion occurs immediately when the clear command is issued. The five-minute WTR period is not needed in this case. If the Force was system-initiated, allow the five-minute waiting period (during WTR) before the reversion occurs.

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Groups area, choose the protection group containing the port you want to clear.

Step 3 In the Selected Group area, choose the port you want to clear.

Step 4 In the Switching Commands area, click Clear.

Step 5 Click Yes in the Confirmation Dialog box.

The Force switch is cleared. Traffic immediately reverts to the working port if the group was configured for revertive switching.

Initiate a Card or Port Lock On Command

Note For a 1+1 optical protection group, only the working port can be placed in the Lock On state.

Step 1 In node view, click the Maintenance > Protection tabs.

Step 2 In the Protection Groups list, click the protection group where you want to apply a lock-on.

Step 3 If you determine that the protect card is in standby mode and you want to apply the lock-on to the protect card, make the protect card active if necessary by completing the following steps:

a. In the Selected Group list, click the protect card.

b. In the Switch Commands area, click Force.

Step 4 In the Selected Group list, click the active card where you want to lock traffic.

Step 5 In the Inhibit Switching area, click Lock On.

Step 5 Right-click a BLSR node west port and choose Set West Protection Operation.

Step 6 In the Set West Protection Operation dialog box, choose Force Ring from the drop-down list.

2.8.3 CTC Card Resetting and Switching

Soft-Reset a Card Using CTC

A soft reset on the active TSC causes the standby TSC card to become active. A soft reset on the preferred copy SSXC causes the alternate copy to come into service. If a line card is reset, there is no resulting traffic switch.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the timing source because the Stratum 3E timing module is being adopted.

Step 1 If you are resetting a TSC card, determine whether it is active and which is standby by positioning the cursor over the active card. An active TSC card has a green ACT/STBY LED illuminated.

Note The TSC card takes several minutes to reboot. Refer to the "Card Features and Functions" chapter in the Cisco ONS 15600 Reference Manual for more information about LED behavior during TSC card reboots.

Step 6 If you reset a TSC card, confirm that it is in standby mode after the reset.

Tip If you run the cursor over the TSC card in CTC, a popup displays the card's status (whether active or standby).

Hard-Reset a Card Using CTC

This procedure is used to force system control from the active TSC card to the standby TSC card, or it is used to reset the SSXC or an optical (traffic) card. This kind of reset reboots the card and clears the flash memory, making it appear like a newly inserted card.

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Caution Use hard resets with caution. There could be up to 15 other sets of bandwidth affected by a hard reset.

Note The hard-reset option is enabled only when the card is placed in the OOS-MA,MT service state.

Note When a TSC card changes from active to standby, the node takes approximately 12 minutes to synchronize completely to the timing source because of the more accurate Stratum 3E timing module being adopted.

Step 1 If you are resetting a TSC card, determine which one is the active card and which is the standby card. (Position the cursor over the active card. An active TSC card has a green ACT/STBY LED illuminated.)

Note The TSC card takes several minutes to reboot. Refer to the "Card Features and Functions" chapter in the Cisco ONS 15600 Reference Manual for more information about LED behavior during TSC card reboots.

Step 6 If you reset a TSC card, confirm that this TSC card you reset is in standby mode.

Tip If you run the cursor over the TSC card in CTC, a popup displays the card's status (whether active or standby).

Request a Cross-Connect Card Preferred Copy Switch

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Step 1 Determine which SSXC card is the preferred copy and which is currently in use.

In node view, click the Maintenance > Preferred Copy tabs.

Step 2 In the Set Preferred drop-down list, select the alternate copy. (For example, if the Slot 8 Copy B is preferred and in use, select the Slot 6 Copy A.)

Caution Do not select the copy that you want to replace.

Step 3 Click Apply.

Step 4 Click Yes in the confirmation dialog box.

Note If you attempt a preferred copy switch and the switch is unsuccessful, it indicates a problem on the alternate SSXC card.

Step 5 Click Refresh until the tab shows that the alternate copy you selected is now the preferred copy. The Currently Used field dynamically changes to display the newly selected preferred copy.

2.8.4 Physical Card Reseating, Resetting, and Replacement

Reset a Card with a Card Pull (Reseat)

Note If you are pulling a TSC card, determine whether a TSC card is active or standby by positioning the cursor over the TSC card graphic to view the status.

Note Resetting a standby TSC card does not change its status to active.

Step 1 Ensure that the card you want to reset is in standby mode.

(A TSC card that is ready for service has a green SRV LED illuminated. An active TSC card has a green ACT/STBY LED illuminated, but a standby card does not have this LED illuminated.)

If you run the cursor over the TSC card in CTC, a popup displays the card's status (whether active or standby).

Step 2 Unlatch the top and bottom ejector levers on the card.

Step 3 Physically pull the card at least partly out of the slot until the lighted LEDs turn off.

Step 4 Wait 30 seconds. Reinsert the card and close the ejector levers.

Note The TSC card takes several minutes to reboot. Refer to the "Card Features and Functions" chapter in the Cisco ONS 15600 Reference Manual for more information about LED behavior during TSC card reboots.

Note When a standby TSC card is removed and reinserted (reseated), all three fan lights might momentarily illuminate, indicating that the fan controller cards have also reset.

Replace an SSXC Card

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note The ONS 15600 system dynamically changes the preferred copy status from one SSXC to the redundant copy if an error is detected on a card port. You can see this change in the CTC node view Maintenance > Preferred Copy window Currently Used field. If errors are detected on both SSXC copies, the Currently Used field says Both.

Note You do not need to make any changes to the database if you are replacing it with a card of exactly the same type.

Note Card removal raises an IMPROPRMVL alarm, but this clears after the card replacement is complete.

Step 1 Physically remove the card to be replaced from the ONS 15600 shelf by completing the following steps:

a. Open the card ejectors.

b. Slide the card out of the slot.

Step 2 Physically replace the SSXC card in the shelf by completing the following steps:

a. Open the ejectors on the replacement card.

b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.

c. Close the ejectors.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Replace an I/O Card

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note Card removal raises an IMPROPRMVL alarm, but this clears after the card replacement is completed.

Step 1 Ensure that the card you are replacing does not carry traffic in a 1+1 protection group by completing the following steps:

a. In node view, click the Maintenance > Protection tabs.

b. Choose the first group listed under Protection Groups.

c. Verify that the slot number for the card you are replacing does not appear in the Selected Groups list. For example, if you are replacing the OC-48 card in Slot 3, ensure Selected Groups does not contain any entries that start with s3, regardless of the port.

Step 2 Ensure that the card you are replacing does not carry path protection circuit traffic by completing the following steps:

Note A port can be part of a 1+1 protection group or part of a path protection, but it cannot be configured for both. However, different ports on one card can be configured in different ways. If you move all of the traffic off some 1+1 ports, you still need to check whether the remaining ports are carrying path protection traffic.

Note If the card you are replacing is not configured for any port or circuit protection, but does carry traffic, bridge and roll this traffic onto another card. Follow the "Bridge and Roll Traffic" procedure in the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide.

Step 3 Ensure that the card you are replacing does not carry BLSR circuit traffic by completing the following steps.

Note If the card you are replacing is not configured for any port or circuit protection, but does carry traffic, bridge and roll this traffic onto another card. Refer to the "Manage Circuits" chapter in the Cisco ONS 15600 Procedure Guide.

Step 4 Remove any fiber optic cables from the ports.

Step 5 Physically remove the card that you want to replace from the ONS 15600 shelf by completing the following steps:

a. Open the card ejectors.

b. Slide the card out of the slot.

Step 6 Physically replace the OC-48 or OC-192 card in the shelf by completing the following steps:

a. Open the ejectors on the replacement card.

b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.

c. Close the ejectors.

Note When you replace a card with the identical type of card, you do not need to make any changes to the database.

Note The TSC card takes several minutes to reboot. Refer to the "Card Features and Functions" chapter in the Cisco ONS 15600 Reference Manual for more information about LED behavior during TSC card reboots.

Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the new system clock source due to the more accurate Stratum 3E timing module being adopted.

Step 2 Confirm that the TSC card you reset is in standby mode after the reset.

A TSC card that is ready for service has a green SRV LED illuminated. An active TSC card has a green ACT/STBY LED illuminated, but a standby card does not have this LED illuminated.

Tip If you run the cursor over the TSC card in CTC, a popup displays the card's status (whether active or standby).

Step 3 Physically remove the card you want to replace from the ONS 15600 by completing the following steps:

a. Open the card ejectors.

b. Slide the card out of the slot.

Step 4 Insert the replacement TSC card into the empty slot by completing the following steps:

a. Open the ejectors on the replacement card.

b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.

c. Close the ejectors.

Step 5 If you want to make the replaced TSC card active, complete Steps b through d in Step 2 again.

Replace an ASAP Carrier Module

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note You do not need to make any changes to the database if you are replacing it with a card of exactly the same type.

Note Card removal raises an IMPROPRMVL alarm, but this clears after the card replacement is completed.

Step 1 Verify that the card is not carrying any traffic. If it is, switch it using the appropriate procedure.

Step 2 Physically remove the ASAP carrier module from the ONS 15600 by completing the following steps:

a. Open the card ejectors.

b. Slide the card out of the slot.

Step 3 Insert the replacement carrier module into the empty slot by completing the following steps:

a. Open the ejectors on the replacement card.

b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.

c. Close the ejectors.

Replace an ASAP 4PIO (PIM) Module

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note You do not need to make any changes to the database if you are replacing it with a card of exactly the same type.

Note Card removal raises an IMPROPRMVL alarm, but this clears after the card replacement is completed.

Step 1 Use a Phillips screwdriver to loosen the screws at the top right and bottom left of the 4PIO (PIM) module.

Step 2 Carefully slide the motherboard of the module along the top and bottom guide rails out of the slot.

Step 3 Carefully slide the motherboard of the new module into the slot.

Step 4 Tighten the screws at the top right and bottom left of the 4PIO (PIM) module.

Note The 4PIO (PIM) LEDs do not light until a fixed-rate PIM is installed in the associated slot or a multirate optical (MRO) PIM is installed and an optical rate is provisioned.

Note If you insert a card into a slot provisioned for a different card, all red LEDs turn on and you will see an MEA alarm for that slot when you open CTC.

Step 5 After you have logged into CTC, verify that the card appears in CTC card view.

Replace an ASAP SFP (PPM) Module

Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard. Statement 206

Note You do not need to make any changes to the database if you are replacing it with a card of exactly the same type.

Note Card removal raises an MPROPRMVL alarm, but this clears after the card replacement is completed.

Step 1 Unlatch the bail clasp by moving it to the left before removing the bad SFP (PPM) from the slot.

Step 2 Slide the SFP (PPM) out of the slot.

Step 3 Verify that the new SFP (PPM) is correct for your network and ASAP card. Refer to the Cisco ONS 15600 Reference Manual for more information.

Step 4 Orient the new SFP so that the Cisco serial number label is facing away from the shelf (to the right).

Step 5 Slide the SFP into the slot and move the bail clasp to the right to secure the SFP.

Caution Do not remove the protective caps until you are ready to attach the network fiber-optic cable.

Note Multirate SFPs (PPMs) must be provisioned in CTC; single-rate SFPs (PPMs) do not need to be provisioned. Refer to the "Install Cards and Fiber-Optic Cable" chapter in the Cisco ONS 15600 Procedure Guide for provisioning instructions.
